The Issue This proceeding concerns Clarence E. Middlebrook's application #2-069- 0785AUSMV for a consumptive use permit for his project at Wekiva Falls Resort. Staff of the St. Johns River Water Management District have recommended approval of the application with certain specific limiting conditions. Petitioner, Middlebrooks, contends that the limitations placed on the approval are inappropriate and are so onerous as to preclude the continued use of his facility for public bathing. Petitioner, STS, claims that the present recreational use is not a reasonable beneficial use, interferes with existing legal users of water and is not in the public interest. STS urges limitations more restrictive than those proposed by the district staff. The basic issue for resolution, therefore, is what conditions should be placed on an approval of Middlebrook's application relating to recreational use. Approval of his application relating to an existing household consumptive use permit is not at issue. The parties have stipulated that STS has standing as a petitioner in this proceeding. In addition, in their prehearing statement filed on August 28, 1989, the parties have stipulated that the 14-inch and 28-inch standpipes on the Wekiva Falls Resort are governed by and subject to the provisions of Chapter 373, F.S., and Chapter 40C-2, F.A.C. and are legally considered to be wells for purposes of this proceeding.
Findings Of Fact In their Prehearing Stipulation filed on August 28, 1989, the parties have agreed: Middlebrooks is a private individual who co- owns, along with his wife, and does business as the Wekiva Falls Resort in Lake County, Florida. STS is the owner of approximately 1,842 acres of land contiguous to the southern and western boundary of the Wekiva Falls Resort. The District, a special taxing district created by Chapter 373, Florida Statutes, is charged with the statutory responsibility of the administration and enforcement of permitting programs pursuant to Part II of Chapter 373, Consumptive Uses of Water, specifically Sections 373-219 and 373.223, Florida Statutes, and Chapter 40C-2, Florida Administrative Code. The District is the agency affected in this proceeding. On September 4, 1985, Petitioner submitted to Respondent a CUP application No. 2-069-0785AUS to withdraw a maximum of .123 million gallons per day (MGD), i.e. 31.7 million gallons per year (MGY) of water for household type use from two standpipes, one 14 inches in diameter and the other 24 inches in diameter, located on Petitioner's property in Lake County, Florida. An administrative hearing was held regarding that application on November 6 and 7, 1986, and a final order was issued on May 14, 1987. The final order was appealed to the Fifth District Court of Appeal which issued its opinion on July 7, 1988 (529 So.2d 1167). Permit No. 2-069-0785AUS was issued by the District as result of these proceedings. Middlebrooks returned the permit by mail to the District. On September 13, 1988, Middlebrooks submitted to Respondent a CUP application No. 2-069-0785AUS to request approval of a maximum of .123 MGD (31.7 MGY) of water for household type use, which was revised on February 21, 1989, to request a maximum 14.26 MGD of water from the two standpipes, one 14 inches in diameter and the other 24 inches in diameter, located on Middlebrooks' property in Lake County, Florida. On March 20, 1989, District's staff gave notice of its intent to recommend approval with conditions of Petitioner's CUP application No. 2-069-0785AUS. Both Middlebrooks' and STS' petitions for administrative hearing were timely filed with the District. In 1968, C.E. Middlebrooks purchased the 140 acre tract on which the wells are located. The property is bounded on the east by the Wekiva River, and on the west by Wekiva River Road. At the time of purchase the property was underdeveloped and overgrown. Shortly after purchase, Middlebrooks inspected the property and found an oval-shaped depression from which water was flowing. Such flow is common in this area along the corridor of the Wekiva basin. These surficial seeps, also called artesian flows, emanate from the surficial and intermediate aquifers. This, and other substantiative findings regarding the characteristics of the property, were made in the recommended order as adopted in the final order in case #86-2101, on May 13, 1987. Still, Petitioner insists that the water was from a natural spring. The only new evidence presented by Petitioner regarding the existence of a "spring" is the testimony of William Shell, who in the late 1930's used to fish with his father in the tributaries and streams off of the Wekiva River. William Shell claims that he and his father took a 10-foot canoe back into the property and he swam and fished in the "spring". Shell was imprecise as to the location of the spring and conceded that the site identified on a map attached to his statement could be as much as five miles off. His testimony as to the existence and location of a spring is unpersuasive in the face of the contrary historical evidence from aerial photographs, soils and geological survey maps, and the well driller's log describing the strata through which the 24-inch well was drilled. In undertaking the development of the property, Middlebrooks dug out the area in which the wells were ultimately drilled, utilizing a dragline to clear out what is now the existing stream bed between the oval-shaped depression and the area which is now the marina (or canoe basin). Extensive dredging was done to develop the marina at a point approximately 200 feet west of the Wekiva River, and additional dredging was done to connect the marina to the Wekiva River in order to have access by boat to the Wekiva River. The stream which now extends from the western boundary to the Wekiva River is called Canoe Creek. In order to maintain the swimming area and the section of Canoe Creek extending eastward from the swimming area to the Wekiva River, it is necessary for Middlebrooks to dredge the area every two to three years. In 1972 as a part of the development activities described above, Middlebrooks hired a well drilling contractor to drill a 14-inch well at a location within the oval-shaped depression. The well was drilled into the Floridan aquifer to a depth of 107 feet, and well casing 14 inches in diameter was driven to a depth of 58 feet. In 1973 Middlebrooks hired a second well drilling contractor to construct a second well within the oval-shaped depression slightly ease of the 14-inch well. The second well was drilled into the Floridan aquifer to a depth of 120 feet, and well casing 24 inches in diameter was driven to a depth of 80 feet. As part of his development activities, Middlebrooks constructed concrete towers around each of the wells and placed diffuser plates and planters on top of each to give the appearance of a waterfall. A concrete wall and sidewalk were constructed around the oval-shaped area. The water flowing from the wells discharges into the oval-shaped swimming area and then flows eastward through Canoe Creek until it reaches the Wekiva River. Middlebrooks' business, known as Wekiva Falls Resort, has a total of 789 campsites located on the northern and southern sides of the property. The swimming area, which extends from the western end of the concrete-enclosed oval- shaped area where the wells are located, to the wooden bridge which crosses Canoe Creek just west of the marina, is licensed by the Florida Department of Health and Rehabilitative Services (HRS) as a public bathing facility. Middlebrooks also offers canoe rentals and paddleboat tours of the Wekiva River, each of which originate from the marina. Middlebrooks' present business operation centers around the water-based recreational opportunities provided by the water emanating from the wells. The facility employs approximately seventeen persons. Groundwater from the Floridan aquifer flows from the two wells under artesian pressure. Middlebrooks testified that he had calculated the discharge from the two wells to be 12.5 mgd and 12.72 mgd, although his records for the period from April 1986 through January 1989 showed average daily flow from the two wells to be 12.98 mgd. The prior final order entered in this matter determined average daily flow to be 12.47 mgd. Because these are artesian wells, flow varies depending on hydrologic conditions. The gate valve for the 24-inch well was frozen in the open position approximately 12 years ago and has since been encased in concrete making it inoperable. There is a diverter valve at water level, which, if opened, would increase the flow volume from the well, but which has no control over the amount of water flowing through the top of the well. As the well is presently structured, water essentially free flows from the well; Middlebrooks can control flow from the 24-inch well only through manual insertion of a poppet valve which must be first hoisted to the top of the well with a crane and then mechanically inserted into the top of the well. The only time this device is used is when Middlebrooks shuts down the well in order to do dredging or other maintenance activities. Early in 1989, the concrete tower encasing the 14- inch well fell over and had to be removed from the swimming area. The well casing was cut off at pool level, removing the gate valve on it. Although flow increased from the 14- inch well as a result of shortening the length of the casing above ground, Middlebrooks mechanically inserted a poppet valve into the top of the remaining casing in order to restrict flow. Middlebrooks contends that, with the restrictor device which is inserted in the 14-inch well, flow is essentially the same as it was before the casing was cut down and the valve removed. In 1973, shortly after the 24-inch well was constructed, USGS did an analysis of the water coming from the well to determine chloride concentrations. Chloride concentrations were measured at that time to be 230 parts per million (ppm). Chloride concentration is a measure of salt content in the water. The benchmark figure for chloride concentration in water as determined by the United States Environmental Protection Agency (EPA) is 250 pp. Water which exceeds 250 ppm in chloride is nonpotable. At the time these wells were drilled, the water was potable. At the base of the Floridan aquifer in the area in which Middlebrooks' property is located is a layer of seawater, extremely high in chloride concentrations, which became trapped when the ocean water which once covered Florida receded and dry land emerged. This water is called relic sea water and is necessarily very old water. Significant discharges through a well in this region can cause the interface between the fresh water in the Floridan aquifer and the relic sea water to move upward toward the cone of influence of the well and break. This is followed by turbulent mixing of relic sea water and fresh water and results in elevated chloride concentrations in the water discharged from the well. This water is sometimes referred to as connate water. Subsequent tests of the chloride concentrations in Middlebrooks' well have been done, both as part of a regional study done by the district and in preparation for this litigation. These test results show significant changes in the chloride concentrations in the water flowing from Middlebrooks' wells. Samples taken by the district in March and October 1986 showed concentrations of 312 ppm in the 14-inch well and 296 ppm for the 24-inch well for March, and 300 ppm for each of the wells in October. The 14-inch well was sampled again by the district in March and April 1989 and showed levels of 335 ppm and 296 ppm respectively, and an April 1989 sample from the 24-inch well showed 317 ppm. Samples taken by Jammal and Associates on August 5, 1989, showed 280 ppm for the 14-inch well and 290 ppm for the 24-inch well. Averaged, these results show concentrations over the 1986-89 period of 304 ppm for the 14-inch well and 300 ppm for the 24-inch well. The changes observed from the 1973 test and the 1986- 89 tests cannot be attributed to seasonal variations. The only samples taken since 1974 from the wells which do not show significant changes in the chloride concentrations are samples which were collected by Middlebrooks himself. The validity of these results is less credible than the results outlined in the previous paragraph, given the expert testimony supporting the former results. Further, the results shown from the samples collected by Middlebrooks are questionable in light of the elevated levels of minerals (including chlorides) which were noted in the analysis of waters taken from Canoe Creek, through which the water coming from the wells flows to the Wekiva River. The water flowing from Canoe Creek is 17 times higher in chlorides than water in the Wekiva River. Chloride levels in the swimming pool area were measured by Dr. Harper at almost 300 ppm. Even Dr. Roessler, an expert called by Middlebrooks noted high levels of mineralization in the water flowing through Canoe Creek to the Wekiva River from the wells and agreed that reductions in flow from the wells would result in reduced chloride concentrations within Canoe Creek. The importance of the significant increase in chloride concentrations in the water flowing from Middlebrooks' wells, as noted, is that the groundwater coming from those wells in no longer potable. Continued discharge from the wells at the current free flow level will aggravate the problem of increasing chloride levels in those wells and in the immediate vicinity of those wells. If no action is taken to address the upward movement of the saltwater-freshwater interface, there is a potential for transmittance of connate water to wells of adjacent landowners. Reduction in the flows from Middlebrooks' wells would stabilize the saltwater-freshwater interface beneath his wells. This could result in lower chloride concentrations in the water flowing from Middlebrooks' wells, and at the very least, there would be no further aggravation of the problem. Section 10D-5.120, Florida Administrative Code, governs public bathing facilities such as Middlebrooks', and essentially has two water quality requirements. The first is a flow-through requirement which specifies that there must be minimum flow of water through the facility of 500 gallons per bather per 24 hours. The second requirement is that total coliforms must not exceed 1000 most probable number of coliform organisms (mpn) per 100 milliliters. Although Middlebrooks' HRS license for his public bathing facility does not limit the number of bathers who may use his facility, there is an existing injunction obtained against Middlebrooks by Lake County, Florida, which allows a maximum of 2500 persons on the entire premises per day. Middlebrooks has made no effort in the past, nor does he presently make any effort to determine how many patrons actually use the bathing facilities on a daily basis. As the prior final order noted "for all the record shows, he may have never had that many (the maximum) since his permit was issued". The only evidence of actual usage of the bathing facilities showed a maximum of 290 persons in the pool area on a summer weekend. Regardless of how few, if any, persons utilize the bathing area under present conditions, the same amount of water flows from the wells daily. The stream which extends from the western end of the swimming area to Wekiva River Road and then off site receives drainage during wet weather conditions from offsite areas. All of Canoe Creek including the portion west of the swimming area is essentially a catch basin for surface water drainage from Middlebrooks' property. Surface water drainage enters Canoe Creek through overland flow, through swales conveying stormwater to it, and through an assortment of stormwater drainpipes which drain parts of Middlebrooks' property as well as off-site areas. The water entering Canoe Creek from this surface water drainage is extremely high in total coliforms. There are no significant stormwater treatment facilities on the site. A concrete weir with a spillway separates the swimming area from Canoe Creek west of the swimming area. The water in Canoe Creek immediately west of the swimming area is extremely high in total coliforms. A sump pump has been installed just west of the weir which, under normal weather conditions, is capable of pumping enough of the water into a roadside swale, thereby diverting it around the swimming area, to prevent this high coliform water from overtopping the weir and flowing into the swimming area. However, under rainfall conditions, the pump will not prevent this drainage from spilling over the weir and Middlebrooks does not run the pump continuously. Water has also been observed spilling over the weir into the swimming area under normal conditions. The higher coliform water which is pumped into the roadside swale is reintroduced into the swimming area through a culvert pipe midway between the oval area, where the wells are located, and the marina. There is also an apparent influx of total coliforms through surficial seepage and other sources internal to Middlebrooks' property. One of these sources of coliforms could be the wastewater treatment plant operated by Middlebrooks on the property. Other than the part-time operation of the sump pump, which was installed for aesthetic reasons rather than water quality reasons, Middlebrooks has done nothing to control the numerous sources of total coliforms to his swimming area, nor does he propose any modifications to accomplish this in his application. Instead he has relied and proposes to continue to rely on the 12.5 mgd flow of water from his wells to dilute the total coliforms entering the swimming area in order to meet the HRS standards for water quality. Middlebrooks dismisses any alterations to the site to address these total coliforms sources as "impractical". To the contrary, it is practical, technologically feasible, and economically feasible to control the introduction of coliform to the swimming area and meet HRS standards by preventing introduction of coliforms rather than relying on massive amounts of groundwater to meet the standards through dilution. One means would be to operate a sump pump around the clock instead of only on a part-time bases. Installation of additional toilet facilities for campers would reduce the use of Canoe Creek and its vicinity as a toilet. More importantly, treatment facilities such as retention and detention areas to treat stormwater runoff before it enters Canoe Creek, as well as diverting the water around the oval part of the swimming area, would enable Middlebrooks to comply with HRS total coliforms standard without the necessity of utilizing 12.5 mgd of groundwater. Reducing the flow of water from Middlebrooks' wells in accordance with the recommendations contained in the District's staff report would not cause blowouts or any other adverse geological consequences on his property or elsewhere. As indicated earlier, this region is characterized by artesian flow, and there is the potential for increased discharges from springs or other discharge points within the vicinity of Middlebrooks' property if flow is reduced from his wells. Overall, the area should return to a more naturally balanced system such as existed before the wells were constructed. The flow which discharges presently through the wells produces enough water to supply the domestic needs of 90,000 people. Reduction in the discharge from the wells would make additional water available for use for other beneficial purposes within the area as the water which now discharges from Middlebrooks' wells could be withdrawn at other locations within the vicinity of Middlebrooks' property. Through properly spacing wells and limiting their depth, (skimming well fields) these other uses of water could occur without aggravating the existing problem with chloride concentrations. Middlebrooks and one of his employees described water upwelling within the swimming area on one occasion when flow was stopped from the wells. While this would not be unusual in an area characterized by artesian flow, it may also be an indication that well construction problems exist with either or both of the wells. Having the wells geophysically logged as is required in the permit conditions proposed by district staff, would reveal, among other things, whether the well is properly grouted and sealed. If the wells are not properly sealed contaminated connate water could be allowed to move upward and interchange with other water-bearing zones, resulting in chloride contamination in those zones as well. The aquatic and wetland habitat associated with Canoe Creek can be divided into three distinct segments: (1) the intermittent stream extending westward from the weir and spillway to Wekiva River Road (hereinafter "the intermittent stream"); (2) the swimming area which begins at the weir and extends to the bridge just west of the marina (hereinafter "the swimming area"); and (3) the marina which encompasses the dredged boat basin and that portion of Canoe Creek extending eastward from the marina. These three segments have varying importance as aquatic or wetland habitats and can be separately characterized according to the impacts which would be felt from a reduction in the flow of water from the wells as recommended by the district staff report. The intermittent stream is characterized by slow flowing or stagnant water. There are species indicative of a wetland system associated with the channel here, although the banks of the stream have been mowed and maintained. Aquatic and wetland dependent species do utilize this part of the stream; however, they are in less abundance than in other parts of Canoe Creek. Because the hydrology of this portion of the stream is not affected by the flow from the wells, there would be no impact on this area if flow from the wells is reduced. The swimming area, which consists entirely of hard sand, is devoid of biological activity as a result of the regular mechanical maintenance performed on it by Middlebrooks, leaving no vegetation in the channel. Although there are aquatic species which utilize primarily the oval-shaped part of the swimming area, many of these are exotic species. In any event, there would continue to be a flow of water to maintain that environment. The southern bank of Canoe Creek in the swimming area down to the water's edge has been cleared, sodded, and is maintained as a lawn. There are no wetland plant species in this area. There are trees along the northern bank of the stream in this area, and it is less disturbed than the southern bank; however, the understory has been removed. Overall, there would be minimal impact to the aquatic and wetland species within the creek itself, and no impact to plant species along the banks of the creek if flows are reduced in accordance with the District staff' s recommendation. The marina area and the creek eastward of it provide the most abundant and productive part of the creek for aquatic species. This portion of the creek is at the same grade as the Wekiva River and therefore is in equilibrium with the river. Water levels are controlled by the pulse of the river, rather than the flow from the wells, and will be unchanged by reduction of flow from the wells. Although there would be a reduction in the amount of water moving through this area, there would be little, if any, impact to the functions of this portion of the creek as an aquatic habitat if the reduction in flow recommended in the district staff report were accomplished. Viewed as a whole, Canoe Creek, because of the wells and the alterations made to the site by Middlebrooks, is an altered natural environment with an artificially created and maintained ecosystem. The primary natural feature associated with this property is the riverine forested wetlands which extend approximately 200 feet inland from the Wekiva River. This area lies within the floodplain of the river and is influenced by the rise and fall of the river. These wetlands would not be affected at all by reduction in flows from the wells. Middlebrooks has contended that the flow from his wells provides a benefit to the Wekiva River by improving water quality in the river. Extensive water quality data showing the quality of discharges from Canoe Creek, versus ambient conditions in the river both upstream and downstream of Canoe Creek, do not support this assertion. The flow from Canoe Creek does not reduce temperatures in the river nor does it provide a thermal refuge for fish. Dissolved oxygen levels in the water flowing out of Canoe Creek are virtually the same as in the Wekiva River upstream of the creek. Chloride concentrations in the Canoe Creek discharge are 17 times higher than in the river itself. Total coliforms are higher in the Canoe Creek discharge than in the river itself. Although there is a slight reduction in nutrients as a result of the Canoe Creek flow, this slight reduction has no impact in a fast moving system such as the Wekiva River. Significantly, the flow from Canoe Creek violates State Water Quality Standards for specific conductivity (an indicator of the level of mineralization.) The probable source of this violation is the mineralized water flowing from Middlebrooks' wells. Reduction in flows from the wells would not degrade water quality in the Wekiva River and would likely eliminate the source of a specific conductance water quality violation. The 12.5 million gallons per day of groundwater which flows through Middlebrooks' wells (as distinguished from the 31.7 million gallons per year that is used for household type use) is primarily used by him to enable him to charge visitors to swim in the water. Any other uses of the water are secondary. The absolute deadline for making application to the District for continuation of existing uses and thereby to be evaluated as an existing legal user was September 11, 1985. The first application filed by Middlebrooks for an allocation of water for a use other than household type use was filed on September 13, 1988, exactly three years after the deadline for the use to be classified as and evaluated as an existing use. No exemption was sought or claimed for the water supplying the swimming area prior to the September 11, 1985, deadline.
Recommendation Based on the foregoing, it is hereby, RECOMMENDED: That a final order be entered by the District Board approving the issuance of a consumptive use permit to C.E. Middlebrooks for the amounts and under the terms and conditions established in the District's Technical Staff Report dated March 24, 1989. DONE AND RECOMMENDED this 31st day of January, 1990, in Tallahassee, Leon County, Florida.

The Issue The issue to be determined is whether Consumptive Use Permit No. 2-083-91926-3, and Environmental Resource Permit No. IND-083-130588-4 should be issued as proposed in the respective proposed agency actions issued by the St. Johns River Water Management District.
Findings Of Fact The Parties Sierra Club, Inc., is a national organization, the mission of which is to explore, enjoy, and advocate for the environment. A substantial number of Sierra Club’s 28,000 Florida members utilize the Silver River, Silver Springs, the Ocklawaha River, and the St. Johns River for water-based recreational activities, which uses include kayaking, swimming, fishing, boating, canoeing, nature photography, and bird watching. St. Johns Riverkeeper, Inc., is one of 280 members of the worldwide Waterkeepers Alliance. Its mission is to protect, restore, and promote healthy waters of the St. Johns River, its tributaries, springs, and wetlands -- including Silver Springs, the Silver River, and the Ocklawaha River -- through citizen- based advocacy. A substantial number of St. Johns Riverkeeper’s more than 1,000 members use and enjoy the St. Johns River, the Silver River, Silver Springs, and the Ocklawaha River for boating, fishing, wildlife observation, and other water-based recreational activities. Karen Ahlers is a native of Putnam County, Florida, and lives approximately 15 miles from the Applicant’s property on which the permitted uses will be conducted. Ms. Ahlers currently uses the Ocklawaha River for canoeing, kayaking, and swimming, and enjoys birding and nature photography on and around the Silver River. Over the years, Ms. Ahlers has advocated for the restoration and protection of the Ocklawaha River, as an individual and as a past-president of the Putnam County Environmental Council. Jeri Baldwin lives on a parcel of property in the northeast corner of Marion County, approximately one mile from the Applicant’s property on which the permitted uses will be conducted. Ms. Baldwin, who was raised in the area, and whose family and she used the resources extensively in earlier years, currently uses the Ocklawaha River for boating. Florida Defenders of the Environment (FDE) is a Florida corporation, the mission of which is to conserve and protect and restore Florida's natural resources and to conduct environmental education projects. A substantial number of FDE’s 186 members, of which 29 reside in Marion County, Florida, use and enjoy Silver Springs, the Silver River, and the Ocklawaha Aquatic Preserve, and their associated watersheds in their educational and outreach activities, as well as for various recreational activities including boating, fishing, wildlife observation, and other water-based recreational activities. Sleepy Creek Lands, LLC (Sleepy Creek or Applicant), is an entity registered with the Florida Department of State to do business in the state of Florida. Sleepy Creek owns approximately 21,000 acres of land in Marion County, Florida, which includes the East Tract and the North Tract on which the activities authorized by the permits are proposed. St. Johns River Water Management District (SJRWMD or District) is a water-management district created by section 373.069(1). It has the responsibility to conserve, protect, manage, and control the water resources within its geographic boundaries. See § 373.069(2)(a), Fla. Stat. The Consumptive Use Permit The CUP is a modification and consolidation of two existing CUP permits, CUP No. 2-083-3011-7 and CUP No. 2-083- 91926-2, which authorize the withdrawal of 1.46 mgd from wells located on the East Tract. Although the existing CUP permits authorize an allocation of 1.46 mgd, actual use has historically been far less, and rarely exceeded 0.3 mgd. The proposed CUP modification will convert the authorized use of water from irrigation of 1,010 acres of sod grass on the East Tract, to supplemental irrigation of improved pasture for grass and other forage crops (approximately 97 percent of the proposed withdrawals) and cattle watering (approximately three percent of the proposed withdrawals) on the North Tract and the East Tract. An additional very small amount will be used in conjunction with the application of agricultural chemicals. CUP No. 2-083-3011-7 is due to expire in 2021. CUP No. 2-083-91926-2 is due to expire in 2024. In addition to the consolidation of the withdrawals into a single permit, the proposed agency action would extend the term of the consolidated permit to 20 years from issuance, with the submission of a compliance report due 10 years from issuance. Sleepy Creek calculated a water demand of 2.569 mgd for the production of grasses and forage crops necessary to meet the needs for grass-fed beef production, based on the expected demand in a 2-in-10 drought year. That calculation is consistent with that established in CUP Applicant’s Handbook (CUP A.H.) section 12.5.1. The calculated amount exceeds the authorized average allocation of 1.46 mgd. Mr. Jenkins testified as to the District’s understanding that the requested amount would be sufficient, since the proposed use was a “scaleable-type project,” with adjustments to cattle numbers made as necessary to meet the availability of feed. Regardless of demand, the proposed permit establishes the enforceable withdrawal limits applicable to the property. With regard to the East Tract, the proposed agency action reduces the existing 1.46 mgd allocation for that tract to a maximum allocation of 0.464 mgd, and authorizes the irrigation of 611 acres of pasture grass using existing extraction wells and six existing pivots. With regard to the North Tract, the proposed agency action authorizes the irrigation of 1,620 acres of pasture and forage grain crops using 15 center pivot systems. Extraction wells to serve the North Tract pivots will be constructed on the North Tract. The proposed North Tract withdrawal wells are further from Silver Springs than the current withdrawal locations. The proposed CUP allows Sleepy Creek to apply the allocated water as it believes to be appropriate to the management of the cattle operation. Although the East Tract is limited to a maximum of 0.464 mgd, there is no limitation on the North Tract. Thus, Sleepy Creek could choose to apply all of the 1.46 mgd on the North Tract. For that reason, the analysis of impacts from the irrigation of the North Tract has generally been based on the full 1.46 mgd allocation being drawn from and applied to the North Tract. The Environmental Resource Permit As initially proposed, the CUP had no elements that would require issuance of an ERP. However, in order to control the potential for increased runoff and nutrient loading resulting from the irrigation of the pastures, Sleepy Creek proposes to construct a stormwater management system to capture runoff from the irrigated pastures, consisting of a series of vegetated upland buffers, retention berms and redistribution swales between the pastures and downgradient wetland features. Because the retention berm and swale system triggered the permitting thresholds in rule 62-330.020(2)(d) (“a total project area of more than one acre”) and rule 62-330.020(2)(e) (“a capability of impounding more than 40 acre-feet of water”), Sleepy Creek was required to obtain an Environmental Resource Permit for its construction. Regional Geologic Features To the west of the North Tract is a geologic feature known as the Ocala Uplift or Ocala Platform, in which the limestone that comprises the Floridan aquifer system exists at or very near the land surface. Karst features, including subterranean conduits and voids that can manifest at the land surface as sinkholes, are common in the Ocala Uplift due in large part to the lack of consolidated or confining material overlaying the limestone. Water falling on the surface of such areas tends to infiltrate rapidly through the soil into the Floridan aquifer, occasionally through direct connections such as sinkholes. The lack of confinement in the Ocala Uplift results in few if any surface-water features such as wetlands, creeks, and streams. As one moves east from the Ocala Uplift, a geologic feature known as the Cody Escarpment becomes more prominent. In the Cody Escarpment, the limestone becomes increasingly overlain by sands, shell, silt, clays, and other less permeable sediments of the Hawthorn Group. The North Tract and the East Tract lie to the east of the point at which the Cody Escarpment becomes apparent. As a result, water tends to flow overland to wetlands and other surface water features. The Property The North and East Tracts are located in northern Marion County near the community of Fort McCoy. East Tract Topography and Historic Use The East Tract is located in the Daisy Creek Basin, and includes the headwaters of a small creek that drains directly to the Ocklawaha River. The historic use of the East Tract has been as a cleared 1,010-acre sod farm. The production of sod included irrigation, fertilization, and pest control. Little change in the topography, use, and appearance of the property will be apparent as a result of the permits at issue, but for the addition of grazing cattle. The current CUPs that are subject to modification in this proceeding authorize groundwater withdrawals for irrigation of the East Tract at the rate of 1.46 mgd. Since the proposed agency action has the result of reducing the maximum withdrawal from wells on the East Tract to 0.464 mgd, thus proportionately reducing the proposed impacts, there was little evidence offered to counter Sleepy Creek’s prima facie case that reasonable assurance was provided that the proposed East Tract groundwater withdrawal allocation will meet applicable CUP standards. There are no stormwater management structures to be constructed on the East Tract. Therefore, the ERP permit discussed herein is not applicable to the East Tract. North Tract Topography and Historic Use The North Tract has a generally flat topography, with elevations ranging from 45 feet to 75 feet above sea level. The land elevation is highest at the center of the North Tract, with the land sloping towards the Ocklawaha River to the east, and to several large wet prairie systems to the west. Surface water features on the North Tract include isolated, prairie, and slough-type wetlands on approximately 28 percent of the North Tract, and a network of creeks, streams, and ditches, including the headwaters of Mill Creek, a contributing tributary of the Ocklawaha River. A seasonal high groundwater elevation on the North Tract is estimated at 6 to 14 inches below ground surface. The existence of defined creeks and surface water features supports a finding that the North Tract is underlain by a relatively impermeable confining layer that impedes the flow of water from the surface and the shallow surficial aquifer to the upper Floridan and lower Floridan aquifers. If there was no confining unit, water going onto the surface of the property, either in the form of rain or irrigation water, would percolate unimpeded to the lower aquifers. Areas in the Ocala Uplift to the west of the North Tract, where the confining layer is thinner and discontiguous, contain few streams or runoff features. Historically, the North Tract was used for timber production, with limited pasture and crop lands. At the time the 7,207-acre North Tract was purchased by Sleepy Creek, land use consisted of 4,061 acres of planted pine, 1,998 acres of wetlands, 750 acres of improved pasture, 286 acres of crops, 78 acres of non-forested uplands, 20 acres of native forest, 10 acres of open water, and 4 acres of roads and facilities. Prior to the submission of the CUP and ERP applications, much of the planted pine was harvested, and the land converted to improved pasture. Areas converted to improved pasture include those proposed for irrigation, which have been developed in the circular configuration necessary for future use with center irrigation pivots. As a result of the harvesting of planted pine, and the conversion of about 345 acres of cropland and non-forested uplands to pasture and incidental uses, total acreage in pasture on the North Tract increased from 750 acres to 3,938 acres. Other improvements were constructed on the North Tract, including the cattle processing facility. Aerial photographs suggest that the conversion of the North Tract to improved pasture and infrastructure to support a cattle ranch is substantially complete. The act of converting the North Tract from a property dominated by planted pine to one dominated by improved pasture, and the change in use of the East Tract from sod farm to pasture, were agricultural activities that did not require a permit from the District. As such, there is no impropriety in considering the actual, legal use of the property in its current configuration as the existing use for which baseline conditions are to be measured. Petitioners argue that the baseline conditions should be measured against the use of the property as planted pine plantation, and that Sleepy Creek should not be allowed to “cattle-up” before submitting its permit applications, thereby allowing the baseline to be established as a higher impact use. However, the applicable rules and statutes provide no retrospective time-period for establishing the nature of a parcel of property other than that lawfully existing when the application is made. See West Coast Reg’l Water Supply Auth. v. SW Fla. Water Mgmt. Dist., Case No. 95-1520 et seq., ¶ 301 (Fla. DOAH May 29, 1997; SFWMD ) (“The baseline against which projected impacts conditions [sic] are those conditions, including previously permitted adverse impacts, which existed at the time of the filing of the renewal applications.”). The evidence and testimony in this case focused on the effects of the water allocation on the Floridan aquifer, Silver Springs, and the Silver River, and on the effects of the irrigation on water and nutrient transport from the properties. It was not directed at establishing a violation of chapter 373, the rules of the SJRWMD, or the CUP Applicant’s Handbook with regard to the use and management of the agriculturally-exempt unirrigated pastures, nor did it do so. Soil Types Soils are subject to classifications developed by the Soil Conservation Service based on their hydrologic characteristics, and are grouped into Group A, Group B, Group C, or Group D. Factors applied to determine the appropriate hydrologic soil group on a site-specific basis include depth to seasonal high saturation, the permeability rate of the most restrictive layer within a certain depth, and the depth to any impermeable layers. Group A includes the most well-drained soils, and Group D includes the most poorly-drained soils. Group D soils are those with seasonal high saturation within 24 inches of the soil surface and a higher runoff potential. The primary information used to determine the hydrologic soil groups on the North Tract was the depth to seasonal-high saturation, defined as the highest expected annual elevation of saturation in the soil. Depth to seasonal-high saturation was measured through a series of seven hand-dug and augered soil borings completed at various locations proposed for irrigation across the North Tract. In determining depth to seasonal-high saturation, the extracted soils were examined based on depth, color, texture, and other relevant characteristics. In six of the seven locations at which soil borings were conducted, a restrictive layer was identified within 36 inches of the soil surface. At one location at the northeastern corner of the North Tract, the auger hole ended at a depth of 48 inches -- the length of the auger -- at which depth there was an observable increase in clay content but not a full restrictive layer. However, while the soil assessment was ongoing, a back-hoe was in operation approximately one hundred yards north of the boring location. Observations of that excavation revealed a heavy clay layer at a depth of approximately 5 feet. In each of the locations, the depth to seasonal-high saturation was within 14 inches of the soil surface. Based on the consistent observation of seasonal-high saturation at each of the sampled locations, as well as the flat topography of the property with surface water features, the soils throughout the property, with the exception of a small area in the vicinity of Pivot 6, were determined to be in hydrologic soil Group D. Hydrogeologic Features There are generally five hydrogeologic units underlying the North Tract, those units being the surficial aquifer system, the intermediate confining unit, the upper Floridan aquifer, the middle confining unit, and the lower Floridan aquifer. In areas in which a confining layer is present, water falling on the surface of the land flows over the surface of the land or across the top of the confining layer. A surficial aquifer, with a relatively high perched water table, is created by the confinement and separation of surface waters from the upper strata of the Floridan aquifer. Surface waters are also collected in or conveyed by various surface water features, including perched wetlands, creeks, and streams. The preponderance of the evidence adduced at the final hearing demonstrates that the surficial aquifer exists on the property to a depth of up to 20 feet below the land surface (bls). Beneath the surficial aquifer is an intermediate confining unit of dense clay interspersed with beds of sand and calcareous clays that exists to a depth of up to 100 feet bls. The clay material observed on the North Tract is known as massive or structureless. Such clays are restrictive with very low levels of hydraulic conductivity, and are not conducive to development of preferential flow paths to the surficial or lower aquifers. The intermediate confining unit beneath the North Tract restricts the exchange of groundwater from the surficial aquifer to the upper Floridan aquifer. The upper Floridan aquifer begins at a depth of approximately 100 feet bls, and extends to a depth of approximately 340 feet bls. At about 340 feet bls, the upper Floridan aquifer transitions to the middle confining unit, which consists of finely grained, denser material that separates the interchange of water between the upper Floridan aquifer and the lower Floridan aquifer. Karst Features Karst features form as a result of water moving through rock that comprises the aquifer, primarily limestone, dissolving and forming conduits in the rock. Karst areas present a challenging environment to simulate through modeling. Models assume the subsurface to be a relatively uniform “sand box” through which it is easier to simulate groundwater flow. However, if the subsurface contains conduits, it becomes more difficult to simulate the preferential flows and their effect on groundwater flow paths and travel times. The District has designated parts of western Alachua County and western Marion County as a Sensitive Karst Area Basin. A Sensitive Karst Area is a location in which the porous limestone of the Floridan aquifer occurs within 20 feet of the land surface, and in which there is 10 to 20 inches of annual recharge to the Floridan aquifer. The designation of an area as being within the Sensitive Karst Area Basin does not demonstrate that it does, or does not, have subsurface features that are karstic in nature, or that would provide a connection between the surficial aquifer and the Floridan aquifer. The western portion of the North Tract is within the Sensitive Karst Area Basin. The two intensive-use areas on the North Tract that have associated stormwater facilities -- the cattle unloading area and the processing facility -- are outside of the Sensitive Karst Area Basin. The evidence was persuasive that karst features are more prominent to the west of the North Tract. In order to evaluate the presence of karst features on the North Tract, Mr. Andreyev performed a “desktop-type evaluation,” with a minimal field survey. The desktop review included a review of aerial photographs and an investigation of available data, including the Florida Geological Survey database of sinkhole occurrence in the area. The aerial photographs showed circular depressions suggestive of karst activity west and southwest of the North Tract, but no such depressions on the North Tract. Soil borings taken on the North Tract indicated the presence of layers of clayey sand, clays, and silts at a depth of 70 to 80 feet. Well-drilling logs taken during the development of the wells used for an aquifer performance test on the North Tract showed the limestone of the Floridan aquifer starting at a depth below ground surface of 70 to 80 feet. Other boring data generated on the North Tract suggests that there is greater than 100 feet of clay and sandy clay overburden above the Floridan aquifer on and in the vicinity of the North Tract. Regardless of site-specific differences, the observed confining layer separating the surficial aquifer from the Floridan aquifer is substantial, and not indicative of a karst environment. Aquifer performance tests performed on the North Tract were consistent in showing that drawdown in the surficial aquifer from the tests was minimal to non-detectable, which is strong evidence of an intact and low-permeability confining layer. The presence of well-developed drainage features on the North Tract is further evidence of a unit of confinement that is restricting water from going deeper into the subsurface, and forcing it to runoff to low-lying surface water features. Petitioners’ witnesses did not perform any site- specific analysis of karst features on or around the Sleepy Creek property. Their understanding of the nature of the karst systems in the region was described as “hypothetical or [] conceptual.” Dr. Kincaid admitted that he knew of no conduits on or adjacent to the North Tract. As a result of the data collected from the North Tract, Mr. Hearn opined that the potential for karst features on the property that provide an opening to the upper Floridan aquifer “is extremely remote.” Mr. Hearn’s opinion is consistent with the preponderance of the evidence in this case, and is accepted. In the event a surface karst feature were to manifest itself, Sleepy Creek has proposed that the surface feature be filled and plugged to reestablish the integrity of the confining layer. More to the point, the development of a surficial karst feature in an area influenced by irrigation would be sufficient grounds for the SJRWMD to reevaluate and modify the CUP to account for any changed conditions affecting the assumptions and bases for issuance of the CUP. Silver Springs, the Silver River, and the Ocklawaha River The primary, almost exclusive concern of Petitioners was the effect of the modified CUP and the nutrients from the proposed cattle ranch on Silver Springs, the Silver River, and the Ocklawaha River. Silver Springs Silver Springs has long been a well-known attraction in Florida. It is located just to the east of Ocala, Florida. Many of the speakers at the public comment period of this proceeding spoke fondly of having frequented Silver Springs over the years, enjoying its crystal clear waters through famous glass-bottomed boats. For most of its recorded history, Silver Springs was the largest spring by volume in Florida. Beginning in the 1970s, it began to lose its advantage, and by the year 2000, Rainbow Springs, located in southwestern Marion County, surpassed Silver Springs as the state’s largest spring. Silver Springs exists at the top of the potentiometric surface of the Floridan aquifer. Being at the “top of the mountain,” when water levels in the Floridan aquifer decline, groundwater flow favors the lower elevation springs. Thus, surrounding springshed boundaries expand to take more water to maintain their baseflows, at the expense of the Silver Springs springshed, which contracts. Rainbow Springs shares an overlapping springshed with Silver Springs. The analogy used by Dr. Knight was of the aquifer as a bucket with holes at different levels, and with the Silver Springs “hole” near the top of the bucket. When the water level in the bucket is high, water will flow from the top hole. As the water level drops below that hole, it will preferentially flow from the lower holes. Rainbow Springs has a vent or outlet from the aquifer, that is 10 feet lower in elevation than that of Silver Springs. Coastal springs are lower still. Thus, as groundwater levels decline, the lower springs “pirate flow” from the upper springs. Since the first major studies of Silver Springs were conducted in the 1950s, the ecosystem of Silver Springs has undergone changes. The water clarity, though still high as compared to other springs, has been reduced by 10 to 15 percent. Since the 1950s, macrophytic plants, i.e., rooted plants with seeds and flowers, have declined in population, while epiphytic and benthic algae have increased. Those plants are sensitive to increases in nitrogen in the water. Thus, Dr. Knight’s opinion that increases in nitrogen emerging from Silver Springs, calculated to have risen from just over 0.4 mg/l in the 1950s, to 1.1 mg/l in 2004, and to up to 1.5 mg/l at present,1/ have caused the observed vegetative changes is accepted. Silver River Silver Springs forms the headwaters for the Silver River, a spring run 5 1/2 miles in length, at which point it becomes a primary input to the Ocklawaha River. Issues of water clarity and alteration of the vegetative regime that exist at Silver Springs are also evident in the Silver River. In addition, the reduction in flow allows for more tannic water to enter the river, further reducing clarity. Dr. Dunn recognized the vegetative changes in the river, and opined that the “hydraulic roughness” caused by the increase in vegetation is likely creating a spring pool backwater at Silver Springs, thereby suppressing some of the flow from the spring. The Silver River has been designated as an Outstanding Florida Water. There are currently no Minimum Flows and Levels established by the District for the Silver River. Ocklawaha River The Ocklawaha River originates near Leesburg, Florida, at the Harris Chain of Lakes, and runs northward past Silver Springs. The Silver River is a major contributor to the flow of the Ocklawaha River. Due to the contribution of the Silver River and other spring-fed tributaries, the Ocklawaha River can take on the appearance of a spring run during periods of low rainfall. Historically, the Ocklawaha River flowed unimpeded to its confluence with the St. Johns River in the vicinity of Palatka, Florida. In the 1960s, as part of the Cross-Florida Barge Canal project, the Rodman Dam was constructed across the Ocklawaha River north of the Sleepy Creek property, creating a large reservoir known as the Rodman Pool. Dr. Knight testified convincingly that the Rodman Dam and Pool have altered the Ocklawaha River ecosystem, precipitating a decline in migratory fish populations and an increase in filamentous algae. At the point at which the Ocklawaha River flows past the Sleepy Creek property, it retains its free-flowing characteristics. Mill Creek, which has its headwaters on the North Tract, is a tributary of the Ocklawaha River. The Ocklawaha River, from the Eureka Dam south, has been designated as an Outstanding Florida Water. However, the Ocklawaha River at the point at which Mill Creek or other potential surface water discharges from the Sleepy Creek property might enter the river are not included in the Outstanding Florida Water designation. There are currently no Minimum Flows and Levels established by the District for the Ocklawaha River. The Silver Springs Springshed A springshed is that area from which a spring draws water. Unlike a surface watershed boundary, which is fixed based on land features, contours, and elevations, a springshed boundary is flexible, and changes depending on a number of factors, including rainfall. As to Silver Springs, its springshed is largest during periods of more abundant rainfall when the aquifer is replenished, and smaller during drier periods when groundwater levels are down, and water moves preferentially to springs and discharge points that are lower in elevation. The evidence in this case was conflicting as to whether the North Tract is in or out of the Silver Springs springshed boundary. Dr. Kincaid indicated that under some of the springshed delineations, part of the North Tract was out of the springshed, but over the total period of record, it is within the springshed. Thus, it was Dr. Kincaid’s opinion that withdrawals anywhere within the region will preferentially impact Silver Springs, though he admitted that he did not have the ability to quantify his opinion. Dr. Knight testified that the North Tract is within the Silver Springs “maximum extent” springshed at least part of the time, if not all the time. He did not opine as to the period of time in which the Silver Springs springshed was at its maximum extent. Dr. Bottcher testified that the North Tract is not within the Silver Springs springshed because there is a piezometric rise between North Tract and Silver Springs. Thus, in his opinion, withdrawals at the North Tract would not be withdrawing water going to Silver Springs. Dr. Dunn agreed that the North Tract is on the groundwater divide for Silver Springs. In his view, the North Tract is sometimes in, and sometimes out of the springshed depending on the potentiometric surface. In his opinion, the greater probability is that the North Tract is more often outside of the Silver Springs springshed, with seasonal and year—to—year variation. Dr. Dunn’s opinion provides the most credible explanation of the extent to which the North Tract sits atop that portion of the lower Floridan aquifer that feeds to Silver Springs. Thus, it is found that the groundwater divide exists to the south of the North Tract for a majority of the time, and water entering the Floridan aquifer from the North Tract will, more often than not, flow away from Silver Springs. Silver Springs Flow Volume The Silver Springs daily water discharge has been monitored and recorded since 1932. Over the longest part of the period of record, up to the 1960s, flows at Silver Springs averaged about 800 cubic feet per second (cfs). Through 1989, there was a reasonable regression between rainfall and springflow, based on average rainfalls. The long-term average rainfall in Ocala was around 50 inches per year, and long-term springflow was about 800 cfs, with deviations from average generally consistent with one another. Between 1990 and 1999, the relationship between rainfall and springflow declined by about 80 cubic feet per second. Thus, with average rainfall of 50 inches per year, the average springflow was reduced to about 720 cfs. From 2000 to 2009, there was an additional decline, such that the total cumulative decline for the 20-year period through 2009 was 250 cfs. Dr. Dunn agreed with Dr. Knight that after 2000, there was an abrupt and persistent reduction in flow of about 165 cfs. However, Dr. Dunn did not believe the post-2000 flow reduction could be explained by rainfall directly, although average rainfall was less than normal. Likewise, groundwater withdrawals did not offer an adequate explanation. Dr. Dunn described a natural 30-year cycle of wetter and drier periods known as the Atlantic Multidecadal Oscillation (AMO) that has manifested itself over the area for the period of record. From the 1940s up through 1970, the area experienced an AMO wet cycle with generally higher than normal rainfall at the Ocala rain station. For the next 30-year period, from 1970 up to 2000, the Ocala area ranged from a little bit drier to some years in which it was very, very dry. Dr. Dunn attributed the 80 cfs decline in Silver Springs flow recorded in the 1990s to that lower rainfall cycle. After 2000, when the next AMO cycle would be expected to build up, as it did post—1940, it did not happen. Rather, there was a particularly dry period around 2000 that Dr. Dunn believes to have had a dramatic effect on the lack of recovery in the post-2000 flows in the Silver River. According to Mr. Jenkins, that period of deficient rainfall extended through 2010. Around the year 2001, the relationship between rainfall and flow changed such that for a given amount of rainfall, there was less flow in the Silver River, with flow dropping to as low as 535 cfs after 2001. It is that reduction in flow that Dr. Knight has attributed to groundwater withdrawals. It should be noted that the observed flow of Silver Springs that formed the 1995 baseline conditions for the North Central Florida groundwater model that will be discussed herein was approximately 706 cfs. At the time of the final hearing in August 2014, flow at Silver Springs was 675 cfs. The reason offered for the apparent partial recovery was higher levels of rainfall, though the issue was not explored in depth. For the ten-year period centered on the year 2000, local water use within Marion and Alachua County, closer to Silver Springs, changed little -- around one percent per year. From a regional perspective, groundwater use declined at about one percent per year for the period from 1990 to 2010. The figures prepared by Dr. Knight demonstrate that the Sleepy Creek project area is in an area that has a very low density of consumptive use permits as compared to areas adjacent to Silver Springs and more clearly in the Silver Springs springshed. In Dr. Dunn’s opinion, there were no significant changes in groundwater use either locally or regionally that would account for the flow reduction in Silver Springs from 1990 to 2010. In that regard, the environmental report prepared by Dr. Dunn and submitted with the CUP modification application estimated that groundwater withdrawals accounted for a reduction in flow at Silver Springs of approximately 20 cfs as measured against the period of record up to the year 2000, with most of that reduction attributable to population growth in Marion County. In the March 2014, environmental impacts report, Dr. Dunn described reductions in the stream flow of not only the Silver River, but of other tributaries of the lower Ocklawaha River, including the upper Ocklawaha River at Moss Bluff and Orange Creek. However, an evaluation of the Ocklawaha River water balance revealed there to be additional flow of approximately 50 cfs coming into the Ocklawaha River at other stations. Dr. Dunn suggested that changes to the vent characteristics of Silver Springs, and the backwater effects of increased vegetation in the Silver River, have resulted in a redistribution of pressure to other smaller springs that discharge to the Ocklawaha River, accounting for a portion of the diminished flow at Silver Springs. The Proposed Cattle Operation Virtually all beef cattle raised in Florida, upon reaching a weight of approximately 875 pounds, are shipped to Texas or Kansas to be fattened on grain to the final body weight of approximately 1,150 pounds, whereupon they are slaughtered and processed. The United States Department of Agriculture has a certification for grass—fed beef which requires that, after an animal is weaned, it can only be fed on green forage crops, including grasses, and on corn and grains that are cut green and before they set seed. The forage crops may be grazed or put into hay or silage and fed when grass and forage is dormant. The benefit of grass feeding is that a higher quality meat is produced, with a corresponding higher market value. Sleepy Creek plans to develop the property as a grass- fed beef production ranch, with pastures and related loading/unloading and slaughter/processing facilities where calves can be fattened on grass and green grain crops to a standard slaughter weight, and then slaughtered and processed locally. By so doing, Sleepy Creek expects to save the transportation and energy costs of shipping calves to the Midwest, and to generate jobs and revenues by employing local people to manage, finish, and process the cattle. As they currently exist, pastures proposed for irrigation have been cleared and seeded, and have “fairly good grass production.” The purpose of the irrigation is to enhance the production and quality of the grass in order to maintain the quality and reliability of feed necessary for the production of grass-fed beef. East Tract Cattle Operation The East Tract is 1,242 acres in size, substantially all of which was previously cleared, irrigated, and used for sod production. The proposed CUP permit authorizes the irrigation of 611 acres of pasture under six existing center pivots. The remaining 631 acres will be used as improved, but unirrigated, pasture. Under the proposed permit, a maximum of 1,207 cattle would be managed on the East Tract. Of that number, 707 cattle would be grazed on the irrigated paddocks, and 500 cattle would be grazed on the unirrigated improved pastures. If the decision is made to forego irrigation on the East Tract, with the water allocation being used on the North Tract or not at all, the number of cattle grazed on the six center pivot pastures would be decreased from 707 cattle to 484 cattle. The historic use of the East Tract as a sod farm resulted in high phosphorus levels in the soil from fertilization, which has made its way to Daisy Creek. Sleepy Creek has proposed a cattle density substantially below that allowed by application of the formulae in the Nutrient Management Plan in order to “mine” the phosphorus levels in the soil over time. North Tract Cattle Operation The larger North Tract includes most of the “new” ranch activities, having no previous irrigation, and having been put to primarily silvicultural use with limited pasture prior to its acquisition by Sleepy Creek. The ranch’s more intensive uses, i.e., the unloading corrals and the slaughter house, are located on the North Tract. The North Tract is 7,207 acres in size. Of that, 1,656 acres are proposed for irrigation by means of 15 center- pivot irrigation systems. In addition to the proposed irrigated pastures, the North Tract includes 2,382 acres of unirrigated improved pasture, of which approximately 10 percent is wooded. Under the proposed permit, a maximum of 6,371 cattle would be managed on the North Tract. Of that number, 3,497 cattle would be grazed on the irrigated paddocks (roughly 2.2 head of cattle per acre), and 2,374 cattle would graze on the improved pastures (up to 1.1 head of cattle per acre). The higher cattle density in the irrigated pastures can be maintained due to the higher quality grass produced as a result of irrigation. The remaining 500 cattle would be held temporarily in high-concentration corrals, either after offloading or while awaiting slaughter. On average, there will be fewer than 250 head of cattle staged in those high-concentration corrals at any one time. In the absence of irrigation, the improved pasture on the North Tract could sustain about 4,585 cattle. Nutrient Management Plan, Water Conservation Plan, and BMPs The CUP and ERP applications find much of their support in the implementation of the Nutrient Management Plan (NMP), the Water Conservation Plan, and Best Management Practices (BMPs). The NMP sets forth information designed to govern the day to day operations of the ranch. Those elements of the NMP that were the subject of substantive testimony and evidence at the hearing are discussed herein. Those elements not discussed herein are found to have been supported by Sleepy Creek’s prima facie case, without a preponderance of competent and substantial evidence to the contrary. The NMP includes a herd management plan, which describes rotational grazing and the movement of cattle from paddock to paddock, and establishes animal densities designed to maintain a balance of nutrients on the paddocks, and to prevent overgrazing. The NMP establishes fertilization practices, with the application of fertilizer based on crop tissue analysis to determine need and amount. Thus, the application of nitrogen- based fertilizer is restricted to that capable of ready uptake by the grasses and forage crops, limiting the amount of excess nitrogen that might run off of the pastures or infiltrate past the root zone. The NMP establishes operation and maintenance plans that incorporate maintenance and calibration of equipment, and management of high-use areas. The NMP requires that records be kept of, among other things, soil testing, nutrient application, herd rotation, application of irrigation water, and laboratory testing. The irrigation plan describes the manner and schedule for the application of water during each irrigation cycle. Irrigation schedules for grazed and cropped scenarios vary from pivot to pivot based primarily on soil type. The center pivots proposed for use employ high-efficiency drop irrigation heads, resulting in an 85 percent system efficiency factor, meaning that there is an expected evaporative loss of 15 percent of the water before it becomes available as water in the soil. That level of efficiency is greater than the system efficiency factor of 80 percent established in CUP A.H. section 12.5.2. Other features of the irrigation plan include the employment of an irrigation manager, installation of an on-site weather station, and cumulative tracking of rain and evapotranspiration with periodic verification of soil moisture conditions. The purpose of the water conservation practices is to avoid over application of water, limiting over-saturation and runoff from the irrigated pastures. Sleepy Creek has entered into a Notice of Intent to Implement Water Quality BMPs with the Florida Department of Agriculture and Consumer Services which is incorporated in the NMP and which requires the implementation of Best Management Practices.2/ Dr. Bottcher testified that implementation and compliance with the Water Quality Best Management Practices manual creates a presumption of compliance with water quality standards. His testimony in that regard is consistent with Department of Agriculture and Consumer Services rule 5M-11.003 (“implementation, in accordance with adopted rules, of BMPs that have been verified by the Florida Department of Environmental Protection as effective in reducing target pollutants provides a presumption of compliance with state water quality standards.”). Rotational Grazing Rotational grazing is a practice by which cattle are allowed to graze a pasture for a limited period of time, after which they are “rotated” to a different pasture. The 1,656 acres proposed for irrigation on the North Tract are to be divided into 15 center-pivot pastures. Each individual pasture will have 10 fenced paddocks. The 611 acres of irrigated pasture on the East Tract are divided into 6 center-pivot pastures. The outer fence for each irrigated pasture is to be a permanent “hard” fence. Separating the internal paddocks will be electric fences that can be lowered to allow cattle to move from paddock to paddock, and then raised after they have moved to the new paddock. The NMP for the North Tract provides that cattle are to be brought into individual irrigated pastures as a single herd of approximately 190 cattle and placed into one of the ten paddocks. They will be moved every one to three days to a new paddock, based upon growing conditions and the reduction in grass height resulting from grazing. In this way, the cattle are rotated within the irrigated pasture, with each paddock being used for one to three days, and then rested until each of the other paddocks have been used, whereupon it will again be used in the rotation. The East Tract NMP generally provides for rotation based on the height of the pasture grasses, but is designed to provide a uniform average of cattle per acre per year. Due to the desire to “mine” phosphorus deposited during the years of operation of the East Tract as a sod farm, the density of cattle on the irrigated East Tract pastures is about 30 percent less than that proposed for the North Tract. The East Tract NMP calls for a routine pasture rest period of 15 to 30 days. Unlike dairy farm pastures, where dairy cows traverse a fixed path to the milking barn several times a day, there will be minimal “travel lanes” within the pastures or between paddocks. There will be no travel lanes through wetlands. If nitrogen-based fertilizer is needed, based upon tissue analysis of the grass, fertilizer is proposed for application immediately after a paddock is vacated by the herd. By so doing, the grass within each paddock will have a sufficient period to grow and “flush up” without grazing or traffic, which results in a high—quality grass when the cattle come back around to feed. Sleepy Creek proposes that rotational grazing is to be practiced on improved pastures and irrigated pastures alike. The rotational practices on the improved East Tract and North Tract pastures are generally similar to those practiced on the irrigated pastures. The paddocks will have permanent watering troughs, with one trough serving two adjacent paddocks. The troughs will be raised to prevent “boggy areas” from forming around the trough. Since the area around the troughs will be of a higher use, Sleepy Creek proposes to periodically remove accumulated manure, and re-grade if necessary. Other cattle support items, including feed bunkers and shade structures are portable and can be moved as conditions demand. Forage Crop Production The primary forage crop on the irrigated pastures is to be Bermuda grass. Bermuda grass or other grass types tolerant of drier conditions will be used in unirrigated pastures. During the winter, when Bermuda grass stops growing, Sleepy Creek will overseed the North Tract pastures with ryegrass or other winter crops. Due to the limitation on irrigation water, the East Tract NMP calls for no over-seeding for production of winter crops. Crops do not grow uniformly during the course of a year. Rather, there are periods during which there are excess crops, and periods during which the crops are not growing enough to keep up with the needs of the cattle. During periods of excess, Sleepy Creek will cut those crops and store them as haylage to be fed to the cattle during lower growth periods. The North Tract management plan allows Sleepy Creek to dedicate one or more irrigated pastures for the exclusive production of haylage. If that option is used, cattle numbers will be reduced in proportion to the number of pastures dedicated to haylage production. As a result of the limit on irrigation, the East Tract NMP does not recommend growing supplemental feed on dedicated irrigation pivot pastures. Direct Wetland Impacts Approximately 100 acres proposed for irrigation are wetlands or wetland buffer. Those areas are predominantly isolated wetlands, though some have surface water connections to Mill Creek, a water of the state. Trees will be cut in the wetlands to allow the pivot to pass overhead. Tree cutting is an exempt agricultural activity that does not require a permit. There was no persuasive evidence that cutting trees will alter the fundamental benefit of the wetlands or damage water resources of the District. The wetlands and wetland buffer will be subject to the same watering and fertigation regimen as the irrigated pastures. The application of water to wetlands, done concurrently with the application of water to the pastures, will occur during periods in which the pasture soils are dry. The incidental application of water to the wetlands during dry periods will serve to maintain hydration of the wetlands, which is considered to be a benefit. Fertilizers will be applied through the irrigation arms, a process known as fertigation. Petitioners asserted that the application of fertilizer onto the wetlands beneath the pivot arms could result in some adverse effects to the wetlands. However, Petitioners did not quantify to what extent the wetlands might be affected, or otherwise describe the potential effects. Fertigation of the wetlands will promote the growth of wetland plants. Nitrogen applied through fertigation will be taken up by plants, or will be subject to denitrification -- a process discussed in greater detail herein -- in the anaerobic wetland soils. The preponderance of the evidence indicated that enhanced wetland plant growth would not rise to a level of concern. Since most of the affected wetlands are isolated wetlands, there is expected to be little or no discharge of nutrients from the wetlands. Even as to those wetlands that have a surface water connection, most, if not all of the additional nitrogen applied through fertigation will be accounted for by the combined effect of plant uptake and denitrification. Larger wetland areas within an irrigated pasture will be fenced at the buffer line to prevent cattle from entering. The NMP provided a blow-up of the proposed fencing related to a larger wetland on Pivot 8. Although other figures are not to the same scale, it appears that larger wetlands associated with Pivots 1, 2, 3, and 12 will be similarly fenced. Cattle would be allowed to go into the smaller, isolated wetlands. Cattle going into wetlands do not necessarily damage the wetlands. Any damage that may occur is a function of density, duration, and the number of cattle. The only direct evidence of potential damage to wetlands was the statement that “[i]f you have 6,371 [cattle] go into a wetland, there may be impacts.” The NMP provides that pasture use will be limited to herds of approximately 190 cattle, which will be rotated from paddock to paddock every two to three days, and which will allow for “rest” periods of approximately 20 days. There will be no travel lanes through any wetland. Thus, there is no evidence to support a finding that the cattle at the density, duration, and number proposed will cause direct adverse effects to wetlands on the property. High Concentration Areas Cattle brought to the facility are to be unloaded from trucks and temporarily corralled for inspection. For that period, the cattle will be tightly confined. Cattle that have reached their slaughter weight will be temporarily held in corrals associated with the processing plant. The stormwater retention ponds used to capture and store runoff from the offloading corral and the processing plant holding corral are part of a normal and customary agricultural activity, and are not part of the applications and approvals that are at issue in this proceeding. The retention ponds associated with the high-intensity areas do not require permits because they do not exceed one acre in size or impound more than 40 acre-feet of water. Nonetheless, issues related to the retention ponds were addressed by Petitioners and Sleepy Creek, and warrant discussion here. The retention ponds are designed to capture 100 percent of the runoff and entrained nutrients from the high concentration areas for a minimum of a 24—hour/25—year storm event. If rainfall occurs in excess of the designed storm, the design is such that upon reaching capacity, only new surface water coming to the retention pond will be discharged, and not that containing high concentrations of nutrients from the initial flush of stormwater runoff. Unlike the stormwater retention berms for the pastures, which are to be constructed from the first nine inches of permeable topsoil on the property, the corral retention ponds are to be excavated to a depth of six feet which, based on soil borings in the vicinity, will leave a minimum of two to four feet of clay beneath the retention ponds. In short, the excavation will penetrate into the clay layer underlying the pond sites, but will not penetrate through that layer. The excavated clay will be used to form the side slopes of the ponds, lining the permeable surficial layer and generally making the ponds impermeable. Organic materials entering the retention ponds will form an additional seal. An organic seal is important in areas in which retention ponds are constructed in sandy soil conditions. Organic sealing is less important in this case, where clay forms the barrier preventing nutrients from entering the surficial aquifer. Although the organic material is subject to periodic removal, the clay layer will remain to provide the impermeable barrier necessary to prevent leakage from the ponds. Dr. Bottcher testified that if, during excavation of the ponds, it was found that the remaining in-situ clay layer was too thin, Sleepy Creek would implement the standard practice of bringing additional clay to the site to ensure adequate thickness of the liner. Nutrient Balance The goal of the NMP is to create a balance of nutrients being applied to and taken up from the property. Nitrogen and phosphorus are the nutrients of primary concern, and are those for which specific management standards are proposed. Nutrient inputs to the NMP consist generally of deposition of cattle manure (which includes solid manure and urine), recycling of plant material and roots from the previous growing season, and application of supplemental fertilizer. Nutrient outputs to the NMP consist generally of volatization of ammonia to the atmosphere, uptake and utilization of the nutrients by the grass and crops, weight gain of the cattle, and absorption and denitrification of the nutrients in the soil. The NMP, and the various models discussed herein, average the grass and forage crop uptake and the manure deposition to match that of a 1,013 pound animal. That average weight takes into account the fact that cattle on the property will range from calf weight of approximately 850 pounds, to slaughter weight of 1150 pounds. Nutrients that are not accounted for in the balance, e.g., those that become entrained in stormwater or that pass through the plant root zone without being taken up, are subject to runoff to surface waters or discharge to groundwater. Generally, phosphorus not taken up by crops remains immobile in the soil. Unless there is a potential for runoff to surface waters, the nutrient balance is limited by the amount of nitrogen that can be taken up by the crops. Due to the composition of the soils on the property, the high water table, and the relatively shallow confining layer, there is a potential for surface runoff. Thus, the NMP was developed using phosphorus as the limiting nutrient, which results in nutrient application being limited by the “P-index.” A total of 108 pounds of phosphorus per acre/per year can be taken up and used by the irrigated pasture grasses and forage crops. Therefore, the total number of cattle that can be supported on the irrigated pastures is that which, as a herd, will deposit an average of 108 pounds of phosphorus per year over the irrigated acreage. Therefore, Sleepy Creek has proposed a herd size and density based on calculations demonstrating that the total phosphorus contained in the waste excreted by the cattle equals the amount taken up by the crops. A herd producing 108 pounds per acre per year of phosphorus is calculated to produce 147 pounds of nitrogen per acre per year. The Bermuda grass and forage crops proposed for the irrigated fields require 420 pounds of nitrogen per acre per year. As a result of the nitrogen deficiency, additional nitrogen-based fertilizer to make up the shortfall is required to maintain the crops. Since phosphorus needs are accounted for by animal deposition, the fertilizer will have no phosphorus. The NMP requires routine soil and plant tissue tests to determine the amount of nitrogen fertilizer needed. By basing the application of nitrogen on measured rather than calculated needs, variations in inputs, including plant decomposition and atmospheric deposition, and outputs, including those affected by weather, can be accounted for, bringing the full nutrient balance into consideration. The numeric values for crop uptakes, manure deposition, and other estimates upon which the NMP was developed were based upon literature, values, and research performed and published by the University of Florida and the Natural Resource Conservation Service. Dr. Bottcher testified convincingly that the use of such values is a proven and reliable method of developing a balance for the operation of similar agricultural operations. A primary criticism of the NMP was its expressed intent to “reduce” or “minimize” the transport of nutrients to surface waters and groundwater, rather than to “negate” or “prevent” such transport. Petitioners argue that complete prevention of the transport of nutrients from the property is necessary to meet the standards necessary for issuance of the CUP and ERP. Mr. Drummond went into some detail regarding the total mass of nutrients expected to be deposited onto the ground from the cattle, exclusive of fertilizer application. In the course of his testimony, he suggested that the majority of the nutrients deposited on the land surface “are going to make it to the surficial aquifer and then be carried either to the Floridan or laterally with the groundwater flow.” However, Mr. Drummond performed no analysis on the fate of nitrogen through uptake by crops, volatization, or soil treatment, and did not quantify the infiltration of nitrogen to groundwater. Furthermore, he was not able to provide any quantifiable estimate on any effect of nutrients on Mill Creek, the Ocklawaha River, or Silver Springs. In light of the effectiveness of the nutrient balance and other elements of the NMP, along with the retention berm system that will be discussed herein, Mr. Drummond’s assessment of the nutrients that might be expected to impact water resources of the District is contrary to the greater weight of the evidence. Mr. Drummond’s testimony also runs counter to that of Dr. Kincaid, who performed a particle track analysis of the fate of water recharge from the North Tract. In short, Dr. Kincaid calculated that of the water that makes it as recharge from the North Tract to the surficial aquifer, less than one percent is expected to make its way to the upper Floridan aquifer, with that portion originating from the vicinity of Pivot 6. Recharge from the other 14 irrigated pastures was ultimately accounted for by evapotranspiration or emerged at the surface and found its way to Mill Creek. The preponderance of the competent, substantial evidence adduced at the final hearing supports the effectiveness of the NMPs for the North Tract and East Tract at managing the application and use of nutrients on the property, and minimizing the transport of nutrients to surface water and groundwater resources of the District. North Central Florida Model All of the experts involved in this proceeding agreed that the use of groundwater models is necessary to simulate what might occur below the surface of the ground. Models represent complex systems by applying data from known conditions and impacts measured over a period of years to simulate the effects of new conditions. Models are imperfect, but are the best means of predicting the effects of stresses on complex and unseen subsurface systems. The North Central Florida (NCF) model is used to simulate impacts of water withdrawals on local and regional groundwater levels and flows. The NCF model simulates the surficial aquifer, the upper Floridan aquifer, and the lower Floridan aquifer. Those aquifers are separated from one another by relatively impervious confining units. The intermediate confining unit separates the surficial aquifer from the upper Floridan aquifer. The intermediate confining unit is not present in all locations simulated by the NCF model. However, the evidence is persuasive that the intermediate confining unit is continuous at the North Tract, and serves to effectively isolate the surficial aquifer from the upper Floridan aquifer. The NCF model is not a perfect depiction of what exists under the land surface of the North Tract or elsewhere. It was, however, acknowledged by the testifying experts in this case, despite disagreements as to the extent of error inherent in the model, to be the best available tool for calculating the effects of withdrawals of water within the boundary of the model. The NCF model was developed and calibrated over a period of years, is updated routinely as data becomes available, and has undergone peer review. Aquifer Performance Tests In order to gather site-specific data regarding the characteristics of the aquifer beneath the Sleepy Creek property, a series of three aquifer performance tests (APTs) was conducted on the North Tract. The first two tests were performed by Sleepy Creek, and the third by the District. An APT serves to induce stress on the aquifer by pumping from a well at a high rate. By observing changes in groundwater levels in observation wells, which can be at varying distances from the extraction well, one can extrapolate the nature of the subsurface. In addition, well-completion reports for the various withdrawal and observation wells provide actual data regarding the composition of subsurface soils, clays, and features of the property. The APT is particularly useful in evaluating the ability of the aquifer to produce water, and in calculating the transmissivity of the aquifer. Transmissivity is a measure of the rate at which a substance passes through a medium and, as relevant to this case, measures how groundwater flows through an aquifer. The APTs demonstrated that the Floridan aquifer is capable of producing water at the rate requested. The APT drawdown contour measured in the upper Floridan aquifer was greater than that predicted from a simple run of the NCF model, but the lateral extent of the drawdown was less than predicted. The most reasonable conclusion to be drawn from the combination of greater than expected drawdown in the upper Floridan aquifer with less than expected extent is that the transmissivity of the aquifer beneath the North Tract is lower than the NCF model assumptions. The conclusion that the transmissivity of the aquifer at the North Tract is lower than previously estimated means that impacts from groundwater extraction would tend to be more vertical than horizontal, i.e., the drawdown would be greater, but would be more localized. As such, for areas of lower than estimated transmissivity, modeling would over-estimate off-site impacts from the extraction. NCF Modeling Scenarios The initial NCF modeling runs were based on an assumed withdrawal of 2.39 mgd, an earlier -- though withdrawn - - proposal. The evidence suggests that the simulated well placement for the 2.39 mgd model run was entirely on the North Tract. Thus, the results of the model based on that withdrawal have some limited relevance, especially given that the proposed CUP allows for all of the requested 1.46 mgd of water to be withdrawn from North Tract wells at the option of Sleepy Creek, but will over-predict impacts from the permitted rate of withdrawal. A factor that was suggested as causing a further over-prediction of drawdown in the 2.39 mgd model run was the decision, made at the request of the District, to exclude the input of data of additional recharge to the surficial aquifer, wetlands and surface waters from the irrigation, and the resulting diminution in soil storage capacity. Although there is some merit to the suggestion that omitting recharge made the model results “excessively conservative,” the addition of recharge to the model would not substantially alter the predicted impacts. A model run was subsequently performed based on a presumed withdrawal of 1.54 mgd, a rate that remains slightly more than, but still representative of, the requested amount of 1.46 mgd. The 1.54 mgd model run included an input for irrigation recharge. The simulated extraction points were placed on the East Tract and North Tract in the general configuration as requested in the CUP application. The NCF is designed to model the impacts of a withdrawal based upon various scenarios, identified at the hearing as Scenarios A, B, C, and D. Scenario A is the baseline condition for the NCF model, and represents the impacts of all legal users of water at their estimated actual flow rates as they existed in 1995. Scenario B is all existing users, not including the applicant, at end-of-permit allocations. Scenario C is all existing users, including the applicant, at current end-of-permit allocations. Scenario D is all permittees at full allocation, except the applicant which is modeled at the requested (i.e., new or modified) end-of-permit allocation. To simulate the effects of the CUP modification, simulations were performed on scenarios A, C, and D. In order to measure the specific impact of the modification of the CUP, the Scenario C impacts to the surficial, upper Floridan, and lower Floridan aquifers were compared with the Scenario D impacts to those aquifers. In order to measure the cumulative impact of the CUP, the Scenario A actual-use baseline condition was compared to the Scenario D condition which predicts the impacts of all permitted users, including the applicant, pumping at full end-of-permit allocations. The results of the NCF modeling indicate the following: 2.39 mgd - Specific Impact The surficial aquifer drawdown from the simulated 2.39 mgd withdrawal was less than 0.05 feet on-site and off- site, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The upper Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at between 0.30 and 0.12 feet on-site, and between 0.30 and 0.01 feet off-site. The higher off-site figures are immediately proximate to the property. The lower Floridan aquifer drawdown from the 2.39 mgd withdrawal was predicted at less than 0.05 feet at all locations, and at or less than 0.02 feet within six miles of the North Tract. 2.39 mgd - Cumulative Impact The cumulative impact to the surficial aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, was less than 0.05 feet on-site, and off-site to the north and east, except to the west of the North Tract, at which a drawdown of 0.07 feet was predicted. The cumulative impact to the upper Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 0.4 feet to 0.8 feet over all pertinent locations. The cumulative impact to the lower Floridan aquifer from all permitted users, including a 2.39 mgd Sleepy Creek withdrawal, ranged from 1.0 to 1.9 feet over all pertinent locations. The conclusion drawn by Mr. Andreyev that the predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals is supported by the evidence and accepted. 1.54 mgd - Specific Impact The NCF model runs based on the more representative 1.54 mgd withdrawal predicted a surficial aquifer drawdown of less than 0.01 feet (i.e., no drawdown contour shown) on the North Tract, and a 0.01 to 0.02 foot drawdown at the location of the East Tract. The drawdown of the upper Floridan aquifer from the CUP modification was predicted at up to 0.07 feet on the property, and generally less than 0.05 feet off-site. There were no drawdown contours at the minimum 0.01 foot level that came within 9 miles of Silver Springs. The lower Floridan aquifer drawdown from the CUP modification was predicted at less than 0.01 feet (i.e., no drawdown contour shown) at all locations. 1.54 mgd - Cumulative Impact A comparison of the cumulative drawdown contours for the 2.36 mgd model and 1.54 mgd model show there to be a significant decrease in predicted drawdowns to the surficial and upper Floridan aquifers, with the decrease in the upper Floridan aquifer drawdown being relatively substantial, i.e., from 0.5 to 0.8 feet on-site predicted for the 2.36 mgd withdrawal, to 0.4 to 0.5 feet on-site for the 1.54 mgd model. Given the small predicted individual impact of the CUP on the upper Floridan aquifer, the evidence is persuasive that the cumulative impacts are the result of other end-of-permit user withdrawals. The drawdown contour for the lower Floridan aquifer predicted by the 1.54 mgd model is almost identical to that of the 2.36 mgd model, thus supporting the conclusion that predicted impacts to the lower Floridan are almost entirely from other end-of-permit user withdrawals. Modeled Effect on Silver Springs As a result of the relocation of the extraction wells from the East Tract to the North Tract, the NCF model run at the 1.54 mgd withdrawal rate predicted springflow at Silver Springs to increase by 0.15 cfs. The net cumulative impact in spring flow as measured from 1995 conditions to the scenario in which all legal users, including Sleepy Creek, are pumping at full capacity at their end-of-permit rates for one year3/ is roughly 35.4 cfs, which is approximately 5 percent of Silver Springs’ current flow. However, as a result of the redistribution of the Sleepy Creek withdrawal, which is, in its current iteration, a legal and permitted use, the cumulative effect of the CUP modification at issue is an increase in flow of 0.l5 cfs. Dr. Kincaid agreed that there is more of an impact to Silver Springs when the pumping allowed by the CUP is located on the East Tract than there is on the North Tract, but that the degree of difference is very small. Dr. Knight testified that effect on the flow of Silver Springs from relocating the 1.46 mgd withdrawal from the East Tract to the North Tract would be “zero.” The predicted increase of 0.15 cfs is admittedly miniscule when compared to the current Silver Springs springflow of approximately 675 cfs. However, as small as the modeled increase may be -- perhaps smaller than its “level of certainty” -- it remains the best evidence that the impact of the CUP modification to the flow of Silver Springs will be insignificant at worst, and beneficial at best. Opposition to the NCF Model Petitioners submitted considerable evidence designed to call the results generated by the District’s and Sleepy Creek’s NCF modeling into question. Karst Features A primary criticism of the validity of the NCF model was its purported inability to account for the presence of karst features, including conduits, and their effect on the results. It was Dr. Kincaid’s opinion that the NCF model assigned transmissivity values that were too high, which he attributed to the presence of karst features that are collecting flow and delivering it to springs. He asserted that, instead of assuming the presence of karst features, the model was adjusted to raise the overall capacity of the porous medium to transmit water, and thereby match the observed flows. In his opinion, the transmissivity values of the equivalent porous media were raised so much that the model can no longer be used to predict drawdowns. That alleged deficiency in the model is insufficient for two reasons. First, as previously discussed in greater detail, the preponderance of the evidence in this case supports a finding that there are no karst features in the vicinity of the North Tract that would provide preferential pathways for water flow so as to skew the results of the NCF model. Second, Dr. Kincaid, while acknowledging that the NCF model is the best available tool for predicting impacts from groundwater extraction on the aquifer, suggested that a hybrid porous media and conduit model would be a better means of predicting impacts, the development of which would take two years or more. There is no basis for the establishment of a de facto moratorium on CUP permitting while waiting for the development of a different and, in this case, unnecessary model. For the reasons set forth herein, it is found that the NCF model is sufficient to accurately and adequately predict the effects of the Sleepy Creek groundwater withdrawals on the aquifers underlying the property, and to provide reasonable assurance that the standards for such withdrawals have been met. Recharge to the Aquifer Petitioners argued that the modeling results showing little significant drawdown were dependent on the application of unrealistic values for recharge or return flow from irrigation. In a groundwater model, as in the physical world, some portion of the water extracted from the aquifer is predicted to be returned to the aquifer as recharge. If more water is applied to the land surface than is being accounted for by evaporation, plant uptake and evapotranspiration, surface runoff, and other processes, that excess water may seep down into the aquifer as recharge. Recharge serves to replenish the aquifer and offset the effects of the groundwater withdrawal. Dr. Kincaid opined that the NCF modeling performed for the CUP application assigned too much water from recharge, offsetting the model's prediction of impacts to other features. It is reasonable to assume that there is some recharge associated with both agricultural and public supply uses. However, the evidence suggests that the impact of recharge on the overall NCF model results is insignificant on the predicted impacts to Silver Springs, the issue of primary concern. Mr. Hearn ran a simulation using the NCF model in which all variables were held constant, except for recharge. The difference between the “with recharge” and “without recharge" simulations at Silver Springs was 0.002 cfs. That difference is not significant, and is not suggestive of adverse impacts on Silver Springs from the CUP modification. Dr. Kincaid testified that “the recharge offset on the property is mostly impacting the surficial aquifer,” and that “the addition of recharge in this case didn't have much of an impact on the upper Floridan aquifer system.” As such, the effect of adding recharge to the model would be as to the effect of groundwater withdrawal on wetlands or surface water bodies, and not on springs. As previously detailed, the drawdown of the surficial aquifer simulated for the 2.39 mgd “no recharge” scenario were less than 0.05 feet on-site and off-site, except for a predicted 0.07 foot drawdown to the west of the North Tract. The predicted drawdown of the surficial aquifer for the 1.54 mgd “with recharge” scenario was 0.02 feet or less. The preponderance of the evidence supports a finding that drawdowns of either degree are less than that at which adverse impacts to wetlands or surface waters would occur. Thus, issues related to the recharge or return flows from irrigation are insufficient to support a finding or conclusion that the NCF model failed to provide reasonable assurance that the standards for issuance of the CUP modification were met. External Boundaries The boundaries of the NCF model are not isolated from the rest of the physical world. Rather, groundwater flows into the modeled area from multiple directions, and out of the modeled area in multiple directions. Inflows to the model area are comprised of recharge, which is an assigned value, and includes water infiltrating and recharging the aquifer from surface waters; injection wells; upward and downward leakage from lower aquifers; and flow across the external horizontal boundaries. Outflows from the model area include evapotranspiration; discharge to surface waters, including springs and rivers; extraction from wells; upward and downward leakage from lower aquifers; and flow against the external model boundaries. Dr. Kincaid testified that flow across the external model boundary is an unknown and unverifiable quantity which increases the uncertainty in the model. He asserted that in the calibrated version of the model, there is no way to check those flows against data. His conclusion was that the inability of the NCF model to accurately account for external boundary flow made the margin of error so great as to make the model an unreliable tool with which to assess whether the withdrawal approved by the proposed CUP modification will increase or decrease drawdown at Silver Springs. The District correlates the NCF model boundaries with a much larger model developed by the United States Geological Survey, the Peninsula of Florida Model, more commonly referred to as the Mega Model, which encompasses most of the State of Florida and part of Southeast Georgia. The Mega Model provides a means to acknowledge that there are stresses outside the NCF model, and to adjust boundary conditions to account for those stresses. The NCF is one of several models that are subsets of the Mega Model, with the grids of the two models being “nested” together. The 1995 base year of the NCF model is sufficiently similar to the 1993-1994 base year of the Mega Model as to allow for a comparison of simulated drawdowns calculated by each of the models. By running a Mega Model simulation of future water use, and applying the change in that use from 1993 base year conditions, the District was able to come to a representative prediction of specific boundary conditions for the 1995 NCF base year, which were then used as the baseline for simulations of subsequent conditions. In its review of the CUP modification, the District conducted a model validation simulation to measure the accuracy of the NCF model against observed conditions, with the conditions of interest being the water flow at Silver Springs. The District ran a simulation using the best information available as to water use in the year 2010, the calculated boundary conditions, irrigation, pumping, recharge, climatic conditions, and generally “everything that we think constitutes that year.” The discharge of water at Silver Springs in 2010 was measured at 580 cfs. The discharge simulated by the NCF model was 545 cfs. Thus, the discharge predicted by the NCF model simulation was within six percent of the observed discharge. Such a result is generally considered in the modeling community to be “a home run.” Petitioners’ objections to the calculation of boundary conditions for the NCF model are insufficient to support a finding that the NCF model is not an appropriate and accurate tool for determining that reasonable assurance has been provided that the standards for issuance of the CUP modification were met. Cumulative Impact Error As part of the District’s efforts to continually refine the NCF, and in conjunction with a draft minimum flows and levels report for Silver Springs and the Silver River, the cumulative NCF model results for the period of baseline to 2010 were compared with the simulated results from the Northern District Model (NDF), a larger model that overlapped the NCF. As a result of the comparison, which yielded different results, it was discovered that the modeler had “turned off” not only the withdrawal pumps, but inputs to the aquifer from drainage wells and sinkholes as well. When those inputs were put back into the model run, and effects calculated only from withdrawals between the “pumps-off” condition and 2010 pumping conditions, the cumulative effect of the withdrawals was adjusted from a reduction in the flow at Silver Springs of 29 cfs to a reduction of between 45 and 50 cfs, an effect described as “counterintuitive.” Although that result has not undergone peer review, and remains subject to further review and comparison with the Mega Model, it was accepted by the District representative, Mr. Bartol. Petitioners seized upon the results of the comparison model run as evidence of the inaccuracy and unreliability of the NCF model. However, the error in the NCF model run was not the result of deficiencies in the model, but was a data input error. Despite the error in the estimate of the cumulative effect of all users at 2010 levels, the evidence in this case does not support a finding that the more recent estimates of specific impact from the CUP at issue were in error. NCF Model Conclusion As has been discussed herein, a model is generally the best means by which to calculate conditions and effects that cannot be directly observed. The NCF model is recognized as being the best tool available for determining the subsurface conditions of the model domain, having been calibrated over a period of years and subject to peer review. It should be recognized that the simulations run using the NCF model represent the worst—case scenario, with all permittees simultaneously drawing at their full end-of-permit allocations. There is merit to the description of that occurrence as being “very remote.” Thus, the results of the modeling represent a conservative estimate of potential drawdown and impacts. While the NCF model is subject to uncertainty, as is any method of predicting the effects of conditions that cannot be seen, the model provides reasonable assurance that the conditions simulated are representative of the conditions that will occur as a result of the withdrawals authorized by the CUP modification. Environmental Resource Permit The irrigation proposed by the CUP will result in runoff from the North Tract irrigated pastures in excess of that expected from the improved pastures, due in large measure to the diminished storage capacity of the soil. Irrigation water will be applied when the soils are dry, and capable of absorbing water not subject to evaporation or plant uptake. The irrigation water will fill the storage space that would exist without irrigation. With irrigation water taking up the capacity of the soil to hold water, soils beneath the irrigation pivots will be less capable of retaining additional moisture during storm events. Thus, there is an increased likelihood of runoff from the irrigated pastures over that expected with dry soils. The increase in runoff is expected to be relatively small, since there should be little or no irrigation needed during the normal summer wet season. The additional runoff may have increased nutrient levels due to the increased cattle density made possible by the irrigation of the pastures. The CUP has a no—impact requirement for water quality resulting from the irrigation of the improved pasture. Thus, nutrients leaving the irrigated pastures may not exceed those calculated to be leaving the existing pre-development use as improved pastures. Retention Berms The additional runoff and nutrient load is proposed to be addressed by constructing a system of retention berms, approximately 50,0004/ feet in length, which is intended to intercept, retain, and provide treatment for runoff from the irrigated pasture. The goal of the system is to ensure that post—development nutrient loading from the proposed irrigated pastures will not exceed the pre—development nutrient loading from the existing improved pastures. An ERP permit is required for the construction of the berm system, since the area needed for the construction of the berms is greater than the one acre in size, and since the berms have the capability of impounding more than 40 acre-feet of water. The berms are to be constructed by excavating the top nine inches of sandy, permeable topsoil and using that permeable soil to create the berms, which will be 1 to 2 feet in height. The water storage areas created by the excavation will have flat or horizontal bottoms, and will be very shallow with the capacity to retain approximately a foot of water. The berms will be planted with pasture grasses after construction to provide vegetative cover. The retention berm system is proposed to be built in segments, with the segment designed to capture runoff from a particular center pivot pasture to be constructed prior to the commencement of irrigation from that center pivot. A continuous clay layer underlies the areas in which the berms are to be constructed. The clay layer varies from 18 to 36 inches below the ground surface, with at least one location being as much as five feet below the ground surface. As such, after nine inches of soil is scraped away to create the water retention area and construct the berm, there will remain a layer of permeable sandy material above the clay. The berms are to be constructed at least 25 feet landward of any jurisdictional wetland, creating a “safe upland line.” Thus, the construction, operation, and maintenance of the retention berms and redistribution swales will result in no direct impacts to jurisdictional wetlands or other surface waters. There will be no agricultural activities, e.g., tilling, planting, or mowing, within the 25-foot buffers, and the buffers will be allowed to establish with native vegetation to provide additional protection for downgradient wetlands. As stormwater runoff flows from the irrigated pastures, it may, in places, create concentrated flow ways. Redistribution swales will be built in those areas to spread any remaining overland flow of water and reestablish sheet flow to the retention berm system. At any point at which water may overtop a berm, the berm will be hardened with rip—rap to insure its integrity. The berms are designed to intercept and collect overland flow from the pastures and temporarily store it behind the berms, regaining the soil storage volume lost through irrigation. A portion of the runoff intercepted by the berm system will evaporate. The majority will infiltrate either through the berm, or vertically into the subsurface soils beneath it. When the surficial soils become saturated, further vertical movement will be stopped by the impermeable clay layer underlying the site. The runoff water will then move horizontally until it reemerges into downstream wetland systems. Thus, the berm system is not expected to have a measurable impact on the hydroperiod of the wetlands on the North Tract. Phosphorus Removal Phosphorus tends to get “tied up” in soil as it moves through it. Phosphorus reduction occurs easily in permeable soil systems because it is removed from the water through a chemical absorption process that is not dependent on the environment of the soil. As the soils in the retention areas and berms go through drying cycles, the absorption capacity is regenerated. Thus, the retention system will effectively account for any increase in phosphorus resulting from the increased cattle density allowed by the irrigation such that there is expected to be no increase in phosphorus levels beyond the berm. Nitrogen Removal When manure is deposited on the ground, primarily as high pH urine, the urea is quickly converted to ammonia, which experiences a loss of 40 to 50 percent of the nitrogen to volatization. Soil conditions during dry weather conditions are generally aerobic. Remaining ammonia in the manure is converted by aerobic bacteria in the soil to nitrates and nitrites. Converted nitrates and nitrites from manure, along with nitrogen from fertilizer, is readily available for uptake as food by plants, including grasses and forage crops. Nitrates and nitrites are mobile in water. Therefore, during rain events of sufficient intensity to create runoff, the nitrogen can be transported downstream towards wetlands and other receiving waters, or percolate downward through the soil until blocked by an impervious barrier. During storm events, the soils above the clay confining layer and the lower parts of the pervious berms become saturated. Those saturated soils are drained of oxygen and become anaerobic. When nitrates and nitrites encounter saturated conditions, they provide food for anaerobic bacteria that exist in those conditions. The bacteria convert nitrates and nitrites to elemental nitrogen, which has no adverse impact on surface waters or groundwater. That process, known as denitrification, is enhanced in the presence of organic material. The soils from which the berms are constructed have a considerable organic component. In addition to the denitrification that occurs in the saturated conditions in and underlying the berms, remaining nitrogen compounds that reemerge into the downstream wetlands are likely to encounter organic wetland-type soil conditions. Organic wetland soils are anaerobic in nature, and will result in further, almost immediate denitrification of the nitrates and nitrites in the emerging water. Calculation of Volume - BMPTRAINS Model The calculation of the volume necessary to capture and store excess runoff from the irrigated pastures was performed by Dr. Wanielista using the BMPTRAINS model. BMPTRAINS is a simple, easy to use spreadsheet model. Its ease of use does not suggest that it is less than reliable. The model has been used as a method of calculating storage volumes in many conditions over a period of more than 40 years. The model was used to calculate the storage volumes necessary to provide storage and treatment of runoff from fifteen “basins” that had a control or a Best Management Practice associated with them. All of the basins were calculated as being underlain by soils in poorly-drained hydrologic soil Group D, except for the basin in the vicinity of Pivot 6, which is underlain by the more well-drained soil Group A. The model assumed about percent of the property to have soil Group A soils, an assumption that is supported by the evidence. Soil moisture conditions on the property were calculated by application of data regarding rainfall events and times, the irrigation schedule, and the amount of irrigation water projected for use over a year. The soil moisture condition was used to determine the amount of water that could be stored in the on-site soils, known as the storage coefficient. Once the storage coefficient was determined, that data was used to calculate the amount of water that would be expected to run off of the North Tract, known as the curve number. The curve number is adjusted by the extent to which the storage within a soil column is filled by the application of irrigation water, making it unable to store additional rainfall. As soil storage goes down, the curve number goes up. Thus, a curve number that approaches 100 means that more water is predicted to run off. Conversely, a lower curve number means that less water is predicted to run off. The pre-development curve number for the North Tract was based on the property being an unirrigated, poor grass area. A post-development curve number was assigned to the property that reflected a wet condition representative of the irrigated soils beneath the pivots. In calculating the storage volume necessary to handle runoff from the basins, the wet condition curve number was adjusted based on the fact that there is a mixture of irrigated and unirrigated general pasture within each basin to be served by a segment of the retention berm system, and by the estimated 15 percent of the time that the irrigation areas would be in a drier condition. In addition, the number was adjusted to reflect the 8 to 10 inches of additional evapotranspiration that occurs as a result of irrigation. The BMPTRAINS model was based on average annual nutrient-loading conditions, with water quality data collected at a suitable point within Reach 22, the receiving waterbody. The effects of nutrients from the irrigated pastures on receiving waterbodies is, in terms of the model, best represented by average annual conditions, rather than a single highest-observed nutrient value. Pre-development loading figures were based on the existing use of the property as unirrigated general pasture. The pre-development phosphorus loading figure was calculated at an average event mean concentration (EMC) of 0.421 milligrams per liter (mg/l). The post—condition phosphorus loading figure was calculated at an EMC of 0.621 mg/l. Therefore, in order to achieve pre-development levels of phosphorus, treatment to achieve a reduction in phosphorus of approximately 36 percent was determined to be necessary. The pre-development nitrogen loading figure was calculated at an EMC of 2.6 mg/l. The post—condition nitrogen loading figure was calculated at an EMC of 3.3 mg/l. Therefore, in order to achieve pre-development levels of nitrogen, treatment to achieve a reduction in nitrogen of approximately 25 percent was determined to be necessary. The limiting value for the design of the retention berms is phosphorus. To achieve post-development concentrations that are equal to or less than pre-development concentrations, the treatment volume of the berm system must be sufficient to allow for the removal of 36 percent of the nutrients in water being retained and treated behind the berms, which represents the necessary percentage of phosphorus. In order to achieve the 36 percent reduction required for phosphorus, the retention berm system must be capable of retaining approximately 38 acre—feet of water from the 15 basins. In order to achieve that retention volume, a berm length of approximately 50,000 linear feet was determined to be necessary, with an average depth of retention behind the berms of one foot. The proposed length of the berms is sufficient to retain the requisite volume of water to achieve a reduction in phosphorus of 36 percent. Thus, the post-development/irrigation levels of phosphorus from runoff are expected to be no greater than pre-development/general pasture levels of phosphorus from runoff. By basing the berm length and volume on that necessary for the treatment of phosphorus, there will be storage volume that is greater than required for a 25 percent reduction in nitrogen. Thus, the post-development/irrigation levels of nitrogen from runoff are expected to be less than pre- development/general pasture levels of nitrogen from runoff. Mr. Drummond admitted that the design of the retention berms “shows there is some reduction, potentially, but it's not going to totally clean up the nutrients.” Such a total clean-up is not required. Rather, it is sufficient that there is nutrient removal to pre-development levels, so that there is no additional pollutant loading from the permitted activities. Reasonable assurance that such additional loading is not expected to occur was provided. Despite Mr. Drummond’s criticism of the BMPTRAINS model, he did not quantify nutrient loading on the North Tract, and was unable to determine whether post-development concentrations of nutrients would increase over pre-development levels. As such, there was insufficient evidence to counter the results of the BMPTRAINS modeling. Watershed Assessment Model In order to further assess potential water quantity and water quality impacts to surface water bodies, and to confirm stormwater retention area and volume necessary to meet pre-development conditions, Sleepy Creek utilized the Watershed Assessment Model (WAM). The WAM is a peer-reviewed model that is widely accepted by national, state, and local regulatory entities. The WAM was designed to simulate water balance and nutrient impacts of varying land uses. It was used in this case to simulate and provide a quantitative measure of the anticipated impacts of irrigation on receiving water bodies, including Mill Creek, Daisy Creek, the Ocklawaha River, and Silver Springs. Inputs to the model include land conditions, soil conditions, rain and climate conditions, and water conveyance systems found on the property. In order to calculate the extent to which nutrients applied to the land surface might affect receiving waters, a time series of surface water and groundwater flow is “routed” through the modeled watershed and to the various outlets from the system, all of which have assimilation algorithms that represent the types of nutrient uptakes expected to occur as water goes through the system. Simulations were performed on the North Tract in its condition prior to acquisition by Sleepy Creek, in its current “exempted improved pasture condition,” and in its proposed “post—development” pivot-irrigation condition. The simulations assessed impacts of the site conditions on surface waters at the point at which they leave the property and discharge to Mill Creek, and at the point where Mill Creek merges into the Ocklawaha River. The baseline condition for measuring changes in nutrient concentrations was determined to be that lawfully existing at the time the application was made. Had there been any suggestion of illegality or impropriety in Sleepy Creek’s actions in clearing the timber and creating improved pasture, a different baseline might be warranted. However, no such illegality or impropriety was shown, and the SJRWMD rules create no procedure for “looking back” to previous land uses and conditions that were legally changed. Thus, the “exempted improved pasture condition” nutrient levels are appropriate for comparison with irrigated pasture nutrient levels. The WAM simulations indicated that nitrogen resulting from the irrigation of the North Tract pastures would be reduced at the outflow to Mill Creek at the Reach 22 stream segment from improved pasture levels by 1.7 percent in pounds per year, and by 0.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 1.3 percent in pounds per year, and 0.5 percent in milligrams per liter of water. These levels are small, but nonetheless support a finding that the berm system is effective in reducing nitrogen from the North Tract. Furthermore, the WAM simulations showed levels of nitrogen from the irrigated pasture after the construction of the retention berms to be reduced from that present in the pre- development condition, a conclusion consistent with that derived from the BMPTRAINS model. The WAM simulations indicated that phosphorus from the irrigated North Tract pastures, measured at the outflow to Mill Creek at the Reach 22 stream segment, would be reduced from improved pasture levels by 3.7 percent in pounds per year, and by 2.6 percent in milligrams per liter of water. The model simulations predicted a corresponding reduction at the Mill Creek outflow to the Ocklawaha River of 2.5 percent in pounds per year, and 1.6 percent in milligrams per liter of water. Those levels are, again, small, but supportive of a finding of no impact from the permitted activities. The WAM simulations showed phosphorus in the Ocklawaha River at the Eureka Station after the construction of the retention berms to be slightly greater than those simulated for the pre-development condition (0.00008 mg/l) -- the only calculated increase. That level is beyond miniscule, with impacts properly characterized as “non- measurable” and “non-detectable.” In any event, total phosphorus remains well below Florida’s nutrient standards. The WAM simulations were conducted based on all of the 15 pivots operating simultaneously at full capacity. That amount is greater than what is allowed under the permit. Thus, according to Dr. Bottcher, the predicted loads are higher than those that would be generated by the permitted allocation, making his estimates “very conservative.” Dr. Bottcher’s testimony is credited. During the course of the final hearing, the accuracy of the model results was questioned based on inaccuracies in rainfall inputs due to the five-mile distance of the property from the nearest rain station. Dr. Bottcher admitted that given the dynamics of summer convection storms, confidence that the rain station rainfall measurements represent specific conditions on the North Tract is limited. However, it remains the best data available. Furthermore, Dr. Bottcher testified that even if specific data points simulated by the model differ from that recorded at the rain station, that same error carries through each of the various scenarios. Thus, for the comparative purpose of the model, the errors get “washed out.” Other testimony regarding purported inaccuracies in the WAM simulations and report were explained as being the result of errors in the parameters used to run alternative simulations or analyze Sleepy Creek’s simulations, including use of soil types that are not representative of the North Tract, and a misunderstanding of dry weight/wet weight loading rates. There was agreement among witnesses that the WAM is regarded, among individuals with expertise in modeling, as an effective tool, and was the appropriate model for use in the ERP application that is the subject of this proceeding. As a result, the undersigned accepts the WAM simulations as being representative of comparative nutrient impacts on receiving surface water bodies resulting from irrigation of the North Tract. The WAM confirmed that the proposed retention berm system will be sufficient to treat additional nutrients that may result from irrigation of the pastures, and supports a finding of reasonable assurance that water quality criteria will be met. With regard to the East Tract, the WAM simulations showed that there would be reductions in nitrogen and phosphorus loading to Daisy Creek from the conversion of the property to irrigated pasture. Those simulations were also conservative because they assumed the maximum number of cattle allowed by the nutrient balance, and did not assume the 30 percent reduction in the number of cattle under the NMP so as to allow existing elevated levels of phosphorus in the soil from the sod farm to be “mined” by vegetation. Pivot 6 The evidence in this case suggests that, unlike the majority of the North Tract, a small area on the western side of the North Tract drains to the west and north. Irrigation Pivot is within that area. Dr. Harper noted that there are some soils in hydrologic soil Group A in the vicinity of Pivot 6 that reflect soils with a deeper water table where rainfall would be expected to infiltrate into the ground. Dr. Kincaid’s particle track analysis suggested that recharge to the surficial aquifer ultimately discharges to Mill Creek, except for recharge at Pivot 11, which is accounted for by evapotranspiration, and recharge at Pivot 6. Dr. Kincaid concluded that approximately 1 percent of the recharge to the surficial aquifer beneath the North Tract found its way into the upper Floridan aquifer. Those particle tracks originated only on the far western side of the property, and implicated only Pivot 6, which is indicative of the flow divide in the Floridan aquifer. Of the 1 percent of particle tracks entering the Floridan aquifer, some ultimately discharged at the St. John’s River, the Ocklawaha River, or Mill Creek. Dr. Kincaid opined, however, that most ultimately found their way to Silver Springs. Given the previous finding that the Floridan aquifer beneath the property is within the Silver Springs springshed for less than a majority of the time, it is found that a correspondingly small fraction of the less than 1 percent of the particle tracks originating on the North Tract, perhaps a few tenths of one percent, can reach Silver Springs. Dr. Bottcher generally agreed that some small percentage of the water from the North Tract may make it to the upper Floridan aquifer, but that amount will be very small. Furthermore, that water reaching the upper Floridan aquifer would have been subject to the protection and treatment afforded by the NMP and the ERP berms. The evidence regarding the somewhat less restrictive confinement of the aquifer around Pivot 6 is not sufficient to rebut the prima facie case that the CUP modification, coupled with the ERP, will meet the District’s permitting standards. Public Interest The primary basis upon which Sleepy Creek relies to demonstrate that the CUP is “consistent with the public interest” is that Florida's economy is highly dependent upon agricultural operations in terms of jobs and economic development, and that there is a necessity of food production. Sleepy Creek could raise cattle on the property using the agriculturally-exempt improved pastures, but the economic return on the investment would be questionable without the increased quality, quantity, and reliability of grass and forage crop production resulting from the proposed irrigation. Sleepy Creek will continue to engage in agricultural activities on its properties if the CUP modification is denied. Although a typical Florida beef operation could be maintained on the property, the investment was based upon having the revenue generation allowed by grass-fed beef production in order to realize a return on its capital investment and to optimize the economic return. If the CUP modification is denied, the existing CUP will continue to allow the extraction of 1.46 mgd for use on the East Tract. The preponderance of the evidence suggests that such a use would have greater impacts on the water levels at Silver Springs, and that the continued use of the East Tract as a less stringently-controlled sod farm would have a greater likelihood of higher nutrient levels, particularly phosphorus levels which are already elevated.

DONE AND ENTERED this 29th day of April, 2015, in Tallahassee, Leon County, Florida. S E. GARY EARLY Administrative Law Judge Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-3060 (850) 488-9675 Fax Filing (850) 921-6847 www.doah.state.fl.us Filed with the Clerk of the Division of Administrative Hearings this 29th day of April, 2015.
Findings Of Fact Based upon the oral and documentary evidence adduced at the final hearing and the entire record in this proceeding, the following findings of fact are made: The SFWMD is a public corporation in the state of Florida existing by virtue of Chapter 25270, Laws of Florida, 1949, and operating pursuant to Chapter 573, Fla. Stat., and Title 40E, Fla. Admin. Code, as a multi-purpose water management district, with its principal office in West Palm Beach, Florida. The Navy has proposed construction of a naval housing facility on the Peary Court site (the "Site") in Key West, Florida. The Site is approximately 25.89 acres and will provide 160 housing units for junior enlisted Navy and Air Force personnel and their families. The Site is the center of a larger, 37 acre drainage basin. The Site was formerly the location of military housing. However, for the past 18 years, the Site had been used by the City of Key West, with the assent of the Navy, for active and passive recreation for city residents. The Site contains a cemetery of historic value and a former military housing structure now being used by the Navy Key West Federal Credit Union with an associated parking area of paved asphalt. On February 6, 1992, the Navy submitted an application for a Surface Water Management District General Permit for the Project. The proposed surface water management system (the "System") was designed by Rice Creekmore, a registered professional engineer, and his company Johnson, Creekmore, and Fabray. The proposed System utilizes the existing topography and incorporates a number of drainage control mechanisms to manage the run-off from the Site. The System employs inlets, swales and culverts to direct stormwater run-off into dry detention areas (ponds) for pretreatment prior to discharging into seven 24-inch Class V injection wells (drainage wells). As discussed below, these injection wells must be permitted by the Florida Department of Environmental Regulation ("FDER"). The dry pond areas utilize key ditches, bottom elevation 1.0' NGVD, in order to hydraulically connect all of the dry pond areas together into one dry system prior to overflowing into the drainage wells beginning at elevation 1.5' NGVD. In other words, the detention ponds are interconnected with pipes. The design includes only one point where run-off would be discharged from the Site during any storm equal to a 25 year, three day storm event. That discharge would occur at the lowest point of the Site at the corner of Eisenhower and Palm. The water would be discharged through a V notch weir (the "Weir") into the City's stormwater system. An existing 12" storm drain line at the discharge point will be replaced by a 13.5" by 22.0" Reinforced Concrete Elliptical Pipe culvert. As discussed in more detail below, the System is designed so as to detain 1" of run-off within the dry detention ponds prior to any discharge through the Weir. After review of the application and submittals, the SFWMD issued a Notice of Intent to issue General Permit and Stormwater Discharge Certification No. 44-00178-S (the "Permit") on September 29, 1992. Petitioner and Intervenor timely petitioned for an administrative hearing challenging the SFWMD decision to award the Permit. There is no dispute as to the standing of either Petitioner or Intervenor. The SFWMD has adopted rules that set forth the criteria which an applicant must satisfy in order for a surface water management permit to issue. The criteria are set forth in Rule 40E-4, Florida Administrative Code. Rule 40E-4.301(1)(m) and 40E-4.091(1)(a) incorporate by reference The Basis of Review for Surface Water Management Permit Applications within South Florida Water Management District - April, 1987, ("The Basis for Review"). The Basis for Review explicates certain procedures and information used by the SFWMD staff in reviewing a surface water management permit application. The SFWMD issues general permits for projects of 40 acres or less that meet specific criteria. All other projects must obtain individual permits which are reviewed by the District Board. The specific rules relating only to general permits are set forth in Rule 40E-40. In addition, the Basis for Review sets forth certain technical requirements which must be met for the issuance of a general permit including general construction requirements and special requirements for wetlands. The Basis for Review also sets forth criteria for how a proposed system should address water quantity and water quality issues. The SFWMD assumes that water quantity and water quality standards will be met if a system satisfies the criteria set forth in the Basis for Review. Water Quantity Criteria Rule 40E-4.301(a), Florida Administrative Code, requires an applicant to provide reasonable assurances that a surface water management system will provide adequate flood protection and drainage. The purpose of the water quantity criteria is to insure that pre- development flows and post-development flows are equal. The SFWMD requires calculations of a project's projected post-development flow to guarantee that the post-development discharge rate will not be in excess of the pre-development discharge rate. These calculations are based on a 25 year, 3 day storm event. There is no stormwater management system in place at the Project Site. The pre-development topography results in a pre-development discharge point from the Site at the corner of Eisenhower Drive and Palm Avenue. At this point, a discharge or outfall pipe leads into the City of Key West's stormwater management system. The City's system ultimately discharge into Garrison Bight, a nearly waterbody which is discussed in more detail below. At the time the Navy began planning for the Project, the Navy was told that the discharge pipe had a capacity of accepting water at a rate of 40 cubic feet per second ("CFS"). The Navy initially designed a system to utilize this capacity. Subsequently, it was discovered that, due to the size of the pipe at the discharge point and the capacity of the pipes downstream in the City of Key West's stormwater management system, the City would not allow or accommodate a discharge of more than 11 CFS from the Site. Thus, the System had to be redesigned so that the discharge to the City's system would not exceed 11 CFS. The system was redesigned to incorporate the seven (7) Class V injection wells. The injection wells are intended to insure that discharge from the Project into the City stormwater system through the surface water discharge pipe at Eisenhower Drive and Palm Avenue will not exceed 11 CFS. The injection wells introduce treated stormwater into the ground before it reaches the discharge point. The pre-development rate of surface water discharge from Peary Court in a 25 year, 72 hour storm event was 55 CFS. This rate was calculated based upon a site survey, a determination of the existing amount of pervious versus impervious surface area, and a calculation made through a generally accepted civil-engineering computer program. 1/ This predevelopment discharge is the amount of water which would be expected to discharge off-site after percolation occurs. The number and size of the injection wells for the proposed system were determined based upon tests of an on-site twelve-inch fire well. The results of the tests revealed that the on-site test well could manage in excess of 2 CFS. Due to test limitations, the exact capacity could not be measured, but the capacity was clearly more than 2 CFS. These results were then compared with data obtained from the engineering firm of Post, Buckeley, Schuh & Jernigan for installed wells in the Florida Keys of a similar nature and size to the wells in the proposed surface water management system. The Post, Buckeley test results indicated that 24-inch wells had a capacity of 31 CFS. In addition, the design engineer consulted with South Florida Well Drillers, who have drilled other wells in the Florida Keys including 24-inch wells at the Key West airport which were completed shortly before the application for this Project. South Florida Well drillers found the capacity of 24-inch wells in Key West to be in the 25 to 30 CFS range. Based upon the results of the test well and the related reports described above, the project engineer based his design of the surface water management system on an estimated well capacity of 8.4 CFS for each well. These estimates were submitted by the Navy in its application and were appropriately determined to be reasonable by the SFWMD staff. Indeed, the evidence established that 8.4 CFS was a conservative estimate. The seven injection wells, at an estimated capacity of approximately 8.4 CFS each, provide in excess of 56 CFS of well discharge capacity, which is beyond the necessary discharge volume for the Project. Limiting Condition No. 13 of the Permit requires the Navy to obtain a well capacity test from a Florida Registered Professional Engineer or Professional Geologist following the installation of the first Class V injection well at the Site. If the results of this test indicate that the capacity of the well is different than that submitted by the Navy in its application, the Navy must apply for a permit modification to provide a design which incorporates a representative injection well flow-rate and an appropriate number of wells for the Site. In view of the reasonableness of the capacity rates utilized for the wells, it is unlikely that the results of the capacity test will result in any major design change in the proposed surface water management system. The use of the injection wells in the proposed surface water management system will significantly reduce the amount of run-off which would otherwise reach Garrison Bight from the Site. After the System is completed, it is expected that the amount of run-off from the Site that will reach Garrison Bight will be only 20 percent of the predevelopment amount. In addition, because there has previously been no management of the run-off from the Site and surrounding areas, there has been a frequent flooding problem at the corner of Eisenhower Drive and Palm Avenue after heavy rain storms. The proposed surface water management system will accommodate the overflow of water which historically occurred when discharges from Peary Court and the surrounding areas could not be accommodated by the Key West storm water management system. Petitioner and Intervenor suggest that the effect of tidal flow on the capacity of the wells was not fully considered. The evidence established that the design engineer considered normal high tides in calculating groundwater elevations. Respondent's engineering experts have concluded that the proposed surface water management system is effectively designed to accommodate the Florida Keys' tidal flows. Petitioner and Intervenor offered no expert testimony to refute this conclusion and/or to establish that the tides would impact the effectiveness of the proposed surface water management system. In the event that an extremely high tide occurs at the time of a storm, the detention ponds may hold standing water for a short time. This water would not be discharged off-site. There is no evidence that tidal influences would in any way adversely affect the System's ability to uptake pollutants in the "first- flush". The Class V shallow injection wells are an integral part of the proposed Peary Court surface water management system. Without the injection wells it is not clear whether the Project could meet the SFWMD water quantity criteria. The SFWMD does not have authority to permit Class V injection wells. FDER must permit those wells. The Peary Court site is not the first Florida Keys' project permitted by the SFWMD which utilizes injection wells. The surface water management permits for the other projects were issued contingent upon obtaining the necessary permits for the injection wells. Special Condition No. 14 of the Permit provides that the Permit is conditioned on the Applicant obtaining the applicable permits from FDER for the injection wells. During the interim while the Navy is seeking the FDER permits, it should be required to retain all run-off on-site. If the Navy is not able to obtain the necessary FDER permits for the injection wells, the Navy should be required to either retain all run-off on-site or propose an alternate design to meet the SFWMD's water quantity requirements. A modified permit application with a new Notice of Intent should be required for any alternate design. The following Special Condition Number 14 was offered by the SFWMD at the hearing (language revised from original condition is highlighted and underlined): THIS PERMIT IS ISSUED BASED ON THE APPLICANT OBTAINING THE NECESSARY CLASS V INJECTION WELL PERMITS FROM THE FLORIDA DEPARTMENT OF ENVIRONMENTAL REGULATION (FDER). THE PERMITTEE SHALL SUBMIT AN APPROVED CLASS V DRAINAGE WELL PERMIT FROM FDER PRIOR TO OPERATION OF THE SURFACE WATER MANAGEMENT SYSTEM. IN THE INTERIM, THE PERMITTEE SHALL CERTIFY TO THE DISTRICT THAT NO OFF-SITE DISCHARGE WILL OCCUR UNTIL THE APPROVED CLASS V DRAINAGE WELLS ARE IN OPERATION. IF THE SURFACE WATER MANAGEMENT SYSTEM DESIGN MUST BE MODIFIED AS A RESULT OF FDER REQUIREMENTS OR IF THE CLASS V INJECTION WELL PERMITS ARE NOT ISSUED, THE APPLICANT SHALL APPLY FOR A PERMIT MODIFICATION TO PROVIDE A SURFACE WATER MANAGEMENT SYSTEM DESIGN WHICH SHALL MEET DISTRICT CRITERIA IN EFFECT AT THAT TIME. The proposed additional language requires the Navy to certify that no off-site discharges will occur until the injection wells are permitted and are operating. This revised language should be added to Special Condition No. 14 to clarify that the injection wells must be in operation prior to any off-site discharge from the surface water management system. Maintenance of the surface water management system entails upkeep of the dry detention areas and routine grass cutting, as well as inspection of the injection wells on a periodic basis to guard against clogging and reduced capacity. The system is essentially designed to operate without direct surveillance or intervention. Injection wells do not require any additional maintenance over and above that which is routinely required for other types of surface water management systems. The injection wells will require routine maintenance to ensure that manholes and inlets do not become clogged. Limiting Condition No. 8 of the Permit requires that the surface water management system, including the injection wells, be maintained. At the hearing, the SFWMD proposed that a condition be added to the Permit to further clarify the maintenance requirements. A condition requiring long-term maintenance would be desirable and reasonable. A new special condition should be added to the Permit requiring long-term maintenance of grass swales and inspections of injection wells for clogging. Acceptable language for such a condition would be: SPECIAL CONDITION NO. 15 The permittee shall provide long-term maintenance of the surface water management system, encompassing the injection wells, including, but not limited to, (a) maintenance of the vegetation in the grass swales and detention ponds and (b) routine inspections of wells and discharge structures for clogging. Water Quality Criteria As noted above, there is no designed system for surface water management and/or water quality pretreatment at the Site in its undeveloped state. Surface water run-off that can not be managed by the City of Key West's storm water management system collects in roads adjacent to the Site, resulting in adverse water quality and quantity impacts to adjacent land and receiving waters. The applicable water quality criteria, contained in Rule 40E-4.301, Florida Administrative Code, require an applicant to provide reasonable assurances that a surface water management system will not cause adverse water quality impacts to receiving waters and adjacent lands, and will not cause discharge which results in any violation of the standards and criteria of Chapter 17-302 for surface waters of the state. Rule 40E-4.301 provides that: In order to obtain a permit under this chapter, an applicant must give reasonable assurances that the surface water management system is consistent with the State Water Policy as set forth in Chapter 17-40, Florida Administrative Code (40E-4.301(1)(h), Florida Administrative Code. Rule 17-40.420 provides in pertinent part: Minimum Stormwater Treatment Performance Standards. When a stormwater management system complies with rules establishing the design and performance criteria for stormwater management systems, there shall be a rebuttable presumption that such systems will comply with state water quality standards. The Department and the Districts, pursuant to Section 373.436, Florida Statutes, shall adopt rules that specify design and performance criteria for new stormwater management systems which: 1. Shall be designed to achieve at least 80 percent reduction of the average annual load of pollutants that would cause or contribute to violations of state water quality standards. The Basis for Review, which is incorporated into Title 40E, Florida Administrative Code, by reference, further delineates the applicable water quality permit criteria for surface water management systems. Regarding water quality criteria, the Basis for Review provides: 3.2.2.1 State standards - Projects shall be designed so that discharges will meet state water quality standards, as set forth in Chapter 17-3 [revised to 17-302], Florida Administrative Code. The SFWMD's water quality criteria do not require chemical testing of stormwater for residential projects. The SFWMD's water quality criteria require that the design of a surface water management system meet applicable design/technology based criteria. Section 3.2.2.2 of the Basis for Review contains the specific water quality criteria for the design of a surface water management system. The SFWMD allows applicants to design their surface water management system using either dry or wet detention or dry or wet retention, so long as the treatment provided by the system meets water quality and quantity criteria. Dry detention consists of a system of grass swales and vegetative- covered ponds which detain water at a predetermined rate prior to off-site discharge. Wet retention can contain canals, ditches, lakes or ponds to retain water on-site. If a system is designed to meet the criteria specified in 3.2.2.2(a) of the Basis for Review and incorporates Best Management Practices ("BMP's") for the type of system proposed, the SFWMD presumes that water quality standards will not be violated. In determining which system is appropriate for a particular site, water quantity (flooding impacts) and water quality impacts must be balanced. In some cases, water quantity concerns may preclude certain types of water quality treatment methods. At the hearing in this case, Petitioner and Intervenor suggested that retention is superior to detention in designing surface water management systems. The evidence presented in this case was insufficient to support this conclusion. In any event, this contention focuses only on water quality considerations. One drawback to retention is that it may have on-site flooding impacts. With respect to this Project, the evidence indicates that retention may not have been an acceptable alternative because of possible adverse water quantity impacts. The Navy's proposed surface water management system was designed to utilize dry detention with filtration for treatment of surface water prior to discharge into the injection wells and/or off-site. The design uses a system of grass swales and grass-covered detention ponds to detain and filter pollutants from the surface water as it makes its way through the dry detention system. The System is designed to utilize as many grass swale areas as possible to filter or treat the surface water before it reaches the detention ponds which provide further treatment. The swales restrict the flow of water to approxmiately one half to one foot per second which allows for percolation and a tremendous amount of filtration. The System utilizes the natural topography of the Site to direct water through the dry detention system to the lowest point of the Site at the corner of Eisenhower Drive and Palm Avenue. Any water which makes it to this last detention pond and is not drained into one of the injection wells can flow through the discharge structure (the Weir) at 11 CFS and ultimately make it into Garrison Bight. Petitioner and Intervenor have suggested that the design of the proposed System is defective because water discharged from the cul-de-sacs in the Project design will flow directly into detention ponds without passing over any of the grass swales. The permit criteria do not specify that all surface water must contact grass swales prior to reaching a detention pond. While greater filtration is achieved the longer the run-off remains in the system, the evidence established that the detention ponds by themselves provide sufficient water quality treatment. With respect to all but one of the cul-de-sacs, the water must pass through at least two detention ponds before it is discharged. Run-off from the cul-de-sac closest to the Weir will receive treatment only in the last discharge pond. Petitioner and Intervenor questioned whether the run- off from this last cul-de-sac will receive adequate treatment, in other words, whether the "first flush" will be adequately detained prior to discharge, especially in circumstances when the detention pond is already wet. However, the evidence was insufficient to establish that their concerns are justified and/or that this situation would constitute a violation of water quality standards. This cul-de-sac is only 100 ft in diameter and accounts for no more than 8 percent of the total run-off from the Site. After considering all of the evidence, it is concluded that the water from the cul-de-sacs will be adequately treated in accordance with the permit criteria prior to any discharge. In assessing the Navy's proposed surface water management system the following criteria from the Basis for Review are pertinent in determining whether the proposed System will provide appropriate water quality treatment: 3.2.2.2 Retention and/or detention in the overall system, including swales, lakes, canals, greenways, etc., shall be provided for one of the three following criteria or equivalent combinations thereof. . .: Wet detention volume shall be provided for the first inch of run-off from the developed project, or the total run-off of 2.5 inches times the percentage of imperviousness, whichever is greater. Dry detention volume shall be provided equal to 75 percent of the above amounts computed for wet detention. If the receiving waterbody, is a "sensitive receiving water," which would include an Outstanding Florida Water, the following additional criteria regarding direct discharges are applicable: 3.2.2.2 d. Projects having greater than 40 percent impervious area and which discharge directly to sensitive receiving waters shall provide at least one half inch of dry detention or retention pretreatment as part of the required retention/detention. The SFWMD interprets the permitting criteria as creating a rebuttable presumption that a surface water management system that provides detention in accordance with BMP's of the first inch (1") of run-off from a Site, commonly referred to as the "first-flush", will meet state water quality standards. The "first-flush" occurs at the onset of a rainfall when most pollutants run off paved areas and percolate into the grass swales. It is an accepted design parameter that the "first flush" contains 90 percent of the pollutants which will be collected in the run-off. The 90 percent of the pollutants in the first flush are consequently retained on-site through pure percolation and never reach the discharge facility. Although Petitioner and Intervenor suggest that dry detention does not provide this degree of filtration, the evidence was insufficient to support this contention. The proposed System for this Project provides treatment for the first one inch (1") of run-off from the developed Project, thereby meeting the permitting criteria for sensitive receiving waters. Intervenor and Petitioner contend that the development of this Project will necessarily result in a larger amount of pollutants in the run-off from the Site. They argue that the Applicant has not provided reasonable assurances that capturing 90 percent of the increased level of pollutants in the first flush will meet water quality standards. As noted above, compliance with the permit criteria creates a rebuttable presumption that water quality standards will be met. Insufficient evidence was presented to overcome this rebuttable presumption. In calculating the appropriate volume for the dry detention ponds, the Project engineer used the Site's percentage of impervious area. The percentage of impervious area was determined in accordance with SFWMD criteria. The calculations do not account for any percolation from the impervious areas even though much of that run-off will pass through swales and other grassy areas of the Site. In addition, there is a built-in buffer between the berm elevation around the ponds and the expected water level in the ponds. These factors confirm that there is significant additional capacity in the ponds which is an overage or safety net. In sizing the detention ponds, the project engineer also factored in additional off-site water that will be coming on-site from Palm Avenue. This water currently ponds on Palm Avenue contributing to a recurring flooding problem in the area. This off-site water will be routed through an inlet and pumped directly into on-site detention areas thereby reducing flooding on Palm Avenue and providing some treatment for off-site run-off that was not previously treated before entering the City's stormwater system. As noted above, additional water quality criteria requirements apply to projects which discharge to an Outstanding Florida Water. These additional criteria are set forth in paragraph 40 above. Outstanding Florida Water or OFW is the designation given exclusively by the FDER to certain waterbodies in Florida which have special significance, either for ecological or recreational reasons. Outstanding Florida Waters are afforded the highest degree of water quality protection. The criteria for designation of waters as Outstanding Florida Waters is found in Chapter 17-302, Florida Administrative Code. When the SFWMD initially reviewed the Permit application for this Project, it erroneously assumed that Garrison Bight, the ultimate receiving body for the waters discharged from the project through the City stormwater system, was an OFW. Although the SFWMD applied water quality criteria for OFW's when it reviewed the subject permit application, the evidence at the hearing in this case established that Garrison Bight is not an Outstanding Florida Water. A FDER representative, qualified as an expert in the designation of Outstanding Florida Waters, testified that the Outstanding Florida Water designation does not apply to certain waterbodies that were degraded at the time of designation or did not have the significance or pristine water quality that merit special protection. The designation also does not apply to artificial waterbodies. Artificial waterbodies are defined in Rule 17-302.700(9)(i), Florida Administrative Code, as a waterbody created by dredging or excavation or by the filing in of its boundaries on at least two sides. The FDER has formally determined that Garrison Bight is not an Outstanding Florida Water because Garrison Bight is an artificial waterbody in accordance with the definition. Furthermore, Garrison Bight is the site of extensive boating and marina activities. The water quality of Garrison Bight is currently degraded in comparison to ambient conditions and offshore/unconfined water. In sum, the evidence established that proposed surface water management system meets or exceeds the current permit criteria. Consequently, the water flowing into Garrison Bight from the Site will be significantly less and much cleaner after the proposed surface water management system is installed than it currently is without a designed surface water management system.
Recommendation Based upon the foregoing Findings of Fact and Conclusions of Law, it is RECOMMENDED that a Final Order be entered approving the issuance of Surface Water Management General Permit No. 44-01785 in accordance with the Notice of Intent dated September 29, 1992 and the additional conditions noted in this Recommended Order. DONE AND ENTERED this 14th day of May, 1993, at Tallahassee, Florida. J. STEPHEN MENTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 14th day of May, 1993.
The Issue The issue for consideration in this proceeding concerns whether the Petitioner is entitled to an on-site sewage disposal system ("OSDS") permit authorizing installation of an OSDS on property which Petitioner owns near the Suwanee River in Dixie County, Florida, in accordance with Section 8l.272, Florida Statutes, and Chapter 10D-6, Florida Administrative Code.
Findings Of Fact The Petitioner is an owner, by joint tenancy, of real property located in Dixie County, Florida, more particularly described as part of Government Lot 1, Section 4, Township 11 South, Range 13 East; closely proximate to the Suwanee River at a location generally known as "New Pine Landing". The surrounding property is characterized by homes and mobile home,;, which have OSDS's installed and operating. The subject property has no improvements constructed thereon, although the Petitioner intends the placement of a 12X60 foot mobile home, containing two bedrooms and one bathroom. There is no OSDS of any type installed on the property at the present time. The subject property is approximately 18.5 acres in size. It was purchased on January 17, 1990, but the property in question has never been platted. On March 20, 1990, the Petitioner made application for an OSDS permit for the aforesaid property, which was denied by the Respondent's letter of denial dated April 23, 1990. The Petitioner was not afforded the opportunity to pursue an informal variance application through the variance procedure set up by the statute and rules cited hereinbelow. Rather, the Respondent, in its denial letter, indicated that, because of the perceived effect of the Governor's Executive Order, discussed hereinbelow, no variances were being granted and the variance procedure would be "bypassed" in favor of affording the Petitioner a formal administrative hearing before the Division of Administrative Hearings concerning the permit denial. The Petitioner testified generally concerning the character of the property in question and the general nature of the terrain and vegetation. The property is characterized by a wetland or swampy area at one end of the property and, in the area of the proposed installation site, the ground elevation is higher, with a benchmark elevation of 8.8 feet above mean sea level ("MSL"), as established by Herbert H. Raker, certified land surveyor, and depicted by Petitioner's Exhibit 2 in evidence. The Petitioner offered no testimony concerning the ground water levels, other than to say that at one point in time, he dug a three-foot-deep hole on the subject property near the septic tank installation site and observed no water in the hole. His testimony did not indicate at what season of the year the observation was made nor whether conditions were wet or dry at the time. The only concrete evidence concerning ground water level at this installation site was that offered by the Respondent, which indicates that the ground water level at the time of the site evaluation was 42 inches below the surface of the property in question at the proposed installation site and, through observation of "mottling1, of the soil, indicating the presence of dampness, that the wet season water table is 12 inches below the surface of the property. Likewise, the Petitioner professed to have no knowledge of the ten-year flood elevation for the property. The Respondent's evidence, derived from materials submitted by the Petitioner in furtherance of the application, consisting of a report from the Suwanee River Water Management District, establishes that the ten-year flood elevation is 14 feet above MSL for Suwanee River Mile 29, which corresponds to the location of the subject property. The property is also located within the regulatory floodway administered by the Suwanee River Water Management District. Rule 10D-6.047, Florida Administrative Code, mandates that before a mounded system for on-site sewage disposal can be installed, a certification by a registered engineer would be necessary to determine that installation of such a mounded system would not raise the level of the "base flood". No such engineering testimony or evidence has been offered in this proceeding, however. The Petitioner further testified in a general sense that it would be a hardship not to be able to) install the OSDS on the property, given the money paid to purchase the property and the intent by the Petitioner to use it for a residence. The Petitioner has no use for the property without being able to use it for a residence. The Petitioner, however, did not offer any testimony or evidence concerning alternatives to installing the proposed OSDS, nor did the Petitioner establish that installation of such a system or an alternative system would pose no adverse health effects on the Petitioner or members of the general public nor that it would pose no degradation to the surface or ground waters involved for purposes of the Petitioner establishing entitlement to a permit or a variance It should be remembered, however, that the Petitioners were not accorded the opportunity to avail themselves of the variance procedure because of the Respondent's interpretation of the Governor's Executive Order 90-14, which it opines precludes it from granting any variances, or permits for OSDS within the ten-year flood elevation. This leads to its advising the Petitioner that to apply for a variance in this instance would be futile. The Governor's Executive Order, which incorporated the "Suwanee River Task Force" recommendation to preclude such system; beneath the ten-year flood elevation was entered on January 17 1990. The Respondent has, in effect, interpreted that Executive Order as precluding it from exercising its discretion to entertain and grant or deny variance applications.
Recommendation Having considered the foregoing Findings of Fact, Conclusions of Law, the evidence of record, the candor and demeanor of the witnesses, and the pleadings and arguments of the parties, it is therefore, RECOMMENDED that a Final Order be entered denying the Petitioner's application for an OSDS permit without prejudice to the Petitioner applying for and seeking a variance from the statutory and rule requirements related to permitting, for the reasons found and concluded above; and without prejudice to pursuing an OSDS permit application at a later time should the Petitioner become able to demonstrate that alternative methods of treatment and disposal of the sewage effluent in question can feasibly be performed within the bounds of the standards enunciated in the above-cited statutes and rules concerning on- site sewage disposal permitting.

Findings Of Fact Upon consideration of the oral and documentary evidence adduced at the hearing, the following relevant fact are found: On May 3, 1989, Cersosimo submitted an application for a Management of Surface Water Permit to the District. Subsequent to the submission of this application, the Polk County Board of County Commissioner (Commissioners) added an additional requirement to Cersosimo's Planned Unit Development (PUD) that there was to be a pre- development/post-development match for basin runoff in the event of a twenty- four hour one hundred (100) year storm event, i.e. following completion of this project (post-development) it will handle the same outflow or flow of storm water for the twenty four-hour one hundred-year storm event as in a pre- development situation. Based on the Commissioners' requirement, the design of the PUD was amended to provide for the required storage capabilities. On July 26, 1990, Cersosimo submitted to the District, its amended application, Management of Surface Water Permit No. 405733.01 incorporating the changes necessitated due to the Commissioners' additional requirement as to storm water runoff. On August 24, 1990, Ramon E. Monreal, P.E., of the Polk County Engineering Division, noted in a letter of that same date referring to Cersosimo's modification of Retention Pond No. 300 for the project in question that "this revision appears to meet the PUD condition by the Board of County Commissioners for drainage and compliance with the Surface Water Management Ordinance". The application of July 26, 1990, amends the original application by superceding and replacing that application. In connection with the application for permit, soil borings were taken at the site location for the retention ponds in order to establish the elevation of the seasonal high water level (SHWL) for that site. The borings indicated an elevation for the SHWL of 110 feet to 112 feet above mean sea level (AMSL). The District conservationally established the elevation for the SHWL of this particular site as 112 feet AMSL. The floor elevation of the lowest retention pond was established at 114.00 feet AMSL. The elevation of the surface of Lake Mabel for the ten year flood warning Level is 114.50 feet AMSL as established by Rule 40D-8.624(1)(z), Florida Administrative Code. District policy requires the floor elevation of a dry retention pond to be a minimum of one foot above the established elevation of the SHWL of that particular site. Even though the surface elevation of Lake Mabel for the Ten Year Flood Warning Level was established as 114.50 feet AMSL, there is insufficient evidence to show that there was lateral migration of water from the lake's edge to the site of the soil borings such that it was evidenced by a demarcation in the soil profile. To the contrary, the evidence shows that there were demarcations in the soil profile to establish an elevation for the SHWL for this site of 110 feet to 112 feet AMSL. The designed weir crest in the lower retention pond, Pond No. 300, has an approximate elevation of 118.50 feet AMSL which prevents water from coming over the top into the pond in the event Lake Mabel reaches the ten year flood level warning elevation of 114.50 feet AMSL. The distance from the present water edge of Lake Mabel to the bottom of Pond No. 300 would be approximately 600 feet, laterally and if the lake reached the ten year flood level warning elevation of 114.50 feet AMSL, the lake's water edge would be approximately 100 feet laterally from the bottom of Pond No. 300. There was sufficient evidence to show that even if the surface elevation of Lake Mabel reached the ten year flood level warning of 114.50 feet AMSL and the SHWL (ground water level) reached 112 feet AMSL, the retention ponds as presently proposed with a floor elevation of 114.00 feet AMSL would still percolate sufficiently, even though the percolation may be diminished from what it would be under present conditions, so that there would still be a pre- development/post-development match for basin runoff. Cersosimo can give reasonable assurances that the surface water management system as presently proposed will not diminish the capabilities of Lake Mabel to fluctuate through the full range established for it in Chapter 40D-8, Florida Administrative Code. Among others, the following specific conditions in pertinent part will be placed on the permit, if granted: . . . The applicant shall visually monitor the ponds on a monthly basis to ensure that the ponds are dry within 36 hours from the end of the last rainfall event. Should the ponds fail to percolate the required water quality volume per District criteria, a permit modification shall be required. . . .

Findings Of Fact On or about May 3, 1978, the petitioner filed with the respondent an application for dredge and fill permits and for a water quality certificate to allow petitioner to complete a planned residential community on and adjacent to Marco Island, Florida. The application encompasses approximately 17,000 acres of petitioner's property, and hundreds of thousands of dollars were expended by petitioner in preparing the application. On November 28, 1979, respondent issued a notice of "intent to deny" the permit application. Among the grounds for denial cited in the nine page "intent to deny" are that the petitioner ". . .has not provided the Department with affirmative reasonable assurance, as required by Subsection 17-4.28(3), Florida Administrative Code, that the immediate and the long-term impacts of this project will not violate State Water Quality Standards." Similar language concerning assurance of water quality standards appears throughout the "intent to deny," as does the Department's assertion of dredge and fill permitting jurisdiction over the proposed development areas. Specific subsections and paragraphs of regulatory rules concerning jurisdiction are not identified in the Department's notice of "intent to deny." The respondent's "intent to deny" is the subject of pending administrative proceedings between these same parties in Division of Administrative Hearings Case Nos. 79-2471 and 80-683. In those proceedings, the petitioner is contesting, inter alia, the Department's application of the rules under challenge herein. By affidavit, the respondent's Chief of the Bureau of Standard Permitting, testified as follows: "I am personally aware that dredge and fill activities often result in violations of water quality standards, result in adverse impacts to and create potentially harmful conditions for animal and plant life, result in the alteration of the chemical, physical and biological integrity of waters, and result in the emission of water contaminants."
Findings Of Fact The petitioner is a private landowner of a tract of land adjacent to the Suwannee River in Dixie County, Florida. The Respondent, State of Florida, Department of Environmental Regulation, is an agency of the State of Florida charged with carrying out the mandates of Chapter 403, Florida Statutes, and the rules contained in the Florida Administrative Code promulgated thereunder. The Petitioner's proposed project entails the construction of a twelve- foot wide filled road across approximately 270 feet of swampy area in which the dominant plant species is bald cypress (taxodium distichum), a species listed in Rule 17-4.02(17), Florida Administrative Code. The property to be so developed by the petitioner lies within the landward extent of the Suwannee River in Dixie County. The Suwannee River, in this project area, constitutes waters of the state over which the Department has dredge and fill permitting jurisdiction pursuant to Rule 17-4.28(a), Florida Administrative Code. The project areas within "outstanding Florida waters" as defined in Rule 17-3.04(1)(3)g, Florida Administrative Code. The "upland berm" or river terrace on the property immediately adjacent to the navigable portion of the river is caused by the natural alluvial deposition of the river and the landward extent of the state waters here involved crosses the property in approximately the center of the parcel. The proposed filing for the road crossing the swamp would result in the permanent elimination of at least 3,240 square feet of area within the landward extent of the Suwannee River. Specifically, the project would consist of a road some 12 feet wide at the bottom and 8 feet wide at the top, extending approximately 270 feet across the swampy area in question from the portion of the property which fronts on a public road, to the river terrace or "berm" area along the navigable portion of the Suwannee River. The road will be constructed with approximately 450 cubic yards of clean fill material with culverts 12 feet in length and 3 feet in diameter placed under the road at 25 foot intervals. The parties have stipulated that the Department has jurisdiction pursuant to Chapter 403, Florida Statutes, and Public Law 92-500, to require a permit and water quality certification or the construction of a stationary installation within the waters of the state which this project has been stipulated to be. The area to be filled is primarily vegetated by bald cypress, ash, blackgum, planer trees and other swamp species falling within the definitional portion of the above rule. The swamp contributes to the maintenance of water quality in the river itself by the filtering of sediment and particulates, assimilating and transforming nutrients and other pollutants through the uptake action of the plant species growing therein. The proposed project would destroy by removal, and by the filling, a substantial number of these species on the site which perform this function. The swamp area also serves as a habitat, food source and breeding ground for various forms of fish and wildlife including a species of state concern, the yellow-crowned night heron, which has been observed on this site and which requires such habitat for breeding and for its food source (see the testimony of Kautz). The area in question provides flood protection by storing flood waters and releasing them in a gradual fashion to the river system, especially during dry periods when the river level is lower than that of the swamp which serves to augment stream flow in such periods. As established by witness Kautz, as well as witnesses Rector and Tyler, the filling proposed by the Petitioner would cause degradation of local water quality within the immediate area where the fill would be placed and, the attendant construction activity adjacent to either side of the filled area would disturb trees, animals and other local biota. The period during and immediately after the construction on the site would be characterized by excessive turbidity and resultant degradation of the water quality within the area and downstream of it. The long-term impact of the project would include continued turbidity adjacent to and downstream from the filled road due to sloughing off of the sides of the road caused by an excessively steep slope and to the necessary maintenance operations required to re-establish the road after washouts caused by each rain or rainy period. An additional long-term detrimental effect will be excessive nutrient enrichment expected in the area due to the removal of the filtrative functions caused by removal of the trees and other plant life across the entire width of the swamp and the resultant inability of the adjacent areas to take up the nutrient load formerly assimilated by the plant life on the project area. The project will thus permanently eradicate the subject area's filtrative and assimilative capacity for nutrients, heavy metals and other pollutants. The effect of this project, as well as the cumulative effect of many such already existent fill roads in this vicinity along the Suwannee River, and the effect of proliferation of such filling, will cause significant degradation of local water quality in violation of state standards. The effect of even this single filled road across the subject swamp is especially severe in terms of its "damming" effect (even with culverts). The resultant retention of water standing in the swamp for excessive periods of time will grossly alter the "hydro period" of the area or the length of time the area is alternately inundated with floodwaters or drained of them. This will cause a severe detrimental effect on various forms of plant and animal life and biological processes necessary to maintenance of adequate water quality in the swamp and in its discharge to the river itself. The excessive retention of floodwaters caused by this damming effect will ultimately result in the death of many of the tree species necessary for the uptake of nutrients and other pollutants which can only tolerate the naturally intermittent and brief flood periods. This permit is not necessary in order for the Petitioner to have access to his property as his parcel fronts on a public access road. The purpose of the proposed road is merely to provide access to the river terrace or "upland berm" area on the portion of the property immediately adjacent to the navigable waters of the Suwannee River. The Department advocated through its various witnesses that a viable and acceptable alternative would be the construction of a walkway or a bridge on pilings across the jurisdictional area in question connecting the two upland portions of Petitioner's property. Such a walkway would also require a permit, but the Department took the position that it would not object to the permitting of an elevated wooden walkway or bridge for vehicles. The petitioner, near the close of the hearing, ultimately agreed that construction of such a walkway or bridge would comport with his wishes and intentions for access to the river berm portion of his property and generally indicated that that approach would be acceptable to him. It should also be pointed out that access is readily available to the waterward portion of the property from the navigable waters of the river by boat. The Petitioner did not refute the evidence propounded by the Department's expert witnesses, but testified that he desired the fill-road alternative because he believed it to be somewhat less expensive than construction of an elevated wooden bridge or walkway and that he had been of the belief that the use of treated pilings for such a walkway or bridge would result in chemical pollution of the state waters in question. The expert testimony propounded by the Respondent, however, establishes that any leaching action of the chemical in treated pilings would have a negligible effect on any life forms in the subject state waters at any measurable distance from the pilings. In summary, the petitioner, although he did not stipulate to amend his petition to allow for construction of the bridge as opposed to the fill road, did not disagree with it as a viable solution and indicated willingness to effect establishment of access to the riverfront portion of his property by that alternative should it be permitted.
Findings Of Fact The Parties and the Property. The Respondent, Saddlebrook Resorts, Inc. (Saddlebrook), is a corporation organized and existing under the laws of Florida, and is wholly owned by the Dempsey family. Saddlebrook is located on approximately 480 acres in central Pasco County, east of I-75 and south of State Road 54. The Petitioner, Wiregrass Ranch, Inc. (Wiregrass) is a corporation organized and existing under the laws of Florida, and is wholly owned by the Porter family ("the Porters"). Wiregrass owns approximately 5,000 acres of property which extends from Saddlebrook west approximately one mile to State Road 581 and south for approximately four miles. The Respondent, the Southwest Florida Water Management District (SWFWMD), is a political subdivision created pursuant to Chapter 61-691, Laws of Florida, which exists and operates under the Water Resources Act, Fla. Stat., Ch. 373. SWFWMD is charged with regulating, among other things, surface water management systems in Pasco County. Saddlebrook discharges surface water onto Wiregrass at two locations on the southern and western boundaries of Saddlebrook, known as the south outfall and the west outfall. Saddlebrook's property is part of a drainage basin totalling approximately 1400 acres that contributes runoff to Wiregrass' property. Until approximately 1973, the Saddlebrook property was undeveloped and owned by the Porters. In approximately 1973, the Porters sold the Saddlebrook property to the Refram family, which began developing the property. In approximately 1979, Saddlebrook acquired the property from the Reframs. The Saddlebrook property includes residential development, a conference center, and golf course and tennis facilities. Wiregrass' property, which is largely undeveloped and used for ranching, consists of pine-palmetto flatwoods, wetland strands, isolated wetlands, and improved pastures. The Porters' Civil Action Against Saddlebrook. The Porters instituted a civil action against Saddlebrook, Porter, et al. v. Saddlebrook Resorts, Inc., Case No. CA 83-1860, in the Circuit Court of the Sixth Judicial District, Pasco County, complaining that post-development discharges from Saddlebrook exceed pre-development discharges. In the civil litigation, the Porters contended that Saddlebrook's peak flow discharges should be returned to pre-development, or 1973, levels. A primary purpose of Saddlebrook's proposed redesign is to return peak flow discharges to those levels that existed in 1973, in response to the Porters' complaints in the civil action. Saddlebrook's current surface water management system is deemed by SWFWMD to be in compliance with Rule 40D-4, and SWFWMD's regulations do not require redesign or modification of the current system. Prior to Saddlebrook's submission of its application, SWFWMD advised Saddlebrook that, because Rule 40D-4 became effective on October 1, 1984, SWFWMD considered that date to be the "pre-development" condition for purposes of evaluating Saddlebrook's discharges. Saddlebrook requested that SWFWMD evaluate its application using 1973 as the pre-development condition. SWFWMD advised Saddlebrook that it would apply 1973 as the pre-development condition if the Porters consented. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for purposes of evaluating those discharges relevant to Saddlebrook's MSSW permit application. Saddlebrook's MSSW Permit Application. On or about February 8, 1990, Saddlebrook submitted its application for MSSW permit no. 497318.00, seeking SWFWMD's conceptual approval of the redesign of Saddlebrook's surface water management system. The proposed redesign calls for modification of most of the existing drainage control structures at Saddlebrook and installation of new control structures at several locations, including the south and west outfalls. After submission of its initial application, Saddlebrook made various subsequent submittals in response to SWFWMD requests for additional information. Saddlebrook's response to SWFWMD's requests culminated in final submittals on March 7, 1991 and April 5, 1991. In its various submittals, Saddlebrook provided, among other things, detailed descriptions of all proposed modifications to its drainage system, engineering reports, and computerized flood-routing analyses of runoff from Saddlebrook under pre-development (1973) and post-modification conditions. Saddlebrook provided all information requested, and SWFWMD thereafter deemed its application complete. SWFWMD's Review of Saddlebrook's Application. In the fifteen months following Saddlwbrook's initial February, 1990, submittal, SWFWMD conducted an intensive review of the application. During the course of this review, SWFWMD staff performed numerous field inspections, made an independent determination of all input data to the computer analyses of Saddlebrook's discharges, and made six separate formal requests for additional information. SWFWMD's requests for additional information required, among other things, that Saddlebrook modify various input data and rerun its computer analyses of discharges under the pre-development and post-modification conditions. In addition, SWFWMD required Saddlebrook to perform computer modelling analyses of discharges from Wiregrass' property onto the property of downstream landowners. Because, unlike the Porters, these downstream owners had not provided consent to use 1973 as the relevant pre-development date, SWFWMD required Saddlebrook to model this downstream discharge using a "pre- development" date of 1984. SWFWMD performed its standard review procedures in connection with Saddlebrooks' application. In addition, SWFWMD also performed its own computer-modelling analyses of Saddlebrook's discharges. This modelling was based on input data independently collected by SWFWMD staff in the field and from other sources. SWFWMD staff also met with the Porters' hydrologist, Dr. Gerald Seaburn, and thoroughly reviewed concerns he expressed in connection with Saddlebrook's application. In addressing these concerns, SWFWMD performed additional work, including conferring with an independent soils expert, performing additional field inspections, and modifying the SWFWMD computer modelling analyses based on alternative input parameters suggested by Dr. Seaburn. In reviewing Saddlebrook's application, SWFWMD applied the design and performance criteria set forth in its "Basis of Review for Surface Water Management Permit Applications" ("Basis of Review"), which is incorporated by reference in F.A.C. Rule Chapter 40D-4. Based upon its review of Saddlebrook's application, SWFWMD concluded that Saddlebrook had demonstrated compliance with the design and performance criteria set forth in SWFWMD's Basis of Review and the conditions for permit issuance under F.A.C. Rule 40D-4.301. By a Staff Report dated April 29, 1991, and Notice of Proposed Agency Action dated May 3, 1991, SWFWMD recommended approval of Saddlebrook's application. Compliance With SWFWMD Permitting Criteria. The design and performance criteria for MSSW permitting set forth in SWFWMD's Basis of Review fall into four categories: (1) water quantity, in terms of peak flow discharges for projects, like Saddlebrook's, located in open drainage basins; (2) flood protection; (3) water quality; and (4) wetlands impacts. Water Quantity. Under the Basis of Review's water quantity standards, SWFWMD requires that projected peak flow discharges during a 25-year, 24-hour storm event under the proposed system be reasonably similar to peak flow discharges under the pre- development condition. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quantity standards. This evidence demonstrated that peak flow discharges during a 25-year, 24-hour storm event under the proposed system will be less than, but reasonably similar to, pre-development (1973) peak flow discharges. The evidence presented at the formal hearing also demonstrated that, under the proposed system, peak flow discharges during a 25-year, 24-hour storm event from Wiregrass' property onto downstream landowners will be less than, but reasonably similar to, 1984 peak flow discharges. The evidence presented by Saddlebrook further demonstrated that storage will be increased under the proposed redesign versus the pre- development, 1973 condition. On Saddlebrook's property, there will be approximately 35 percent more storage than existed in 1973, and the total storage for Saddlebrook and the contributing drainage basin upstream of Saddlebrook will be increased by approximately 15 percent over that existing in 1973. Flood Protection. Under the flood-protection standards of the Basis of Review, SWFWMD requires that the applicant demonstrate that under the proposed condition the lower floor of all residential and other buildings on-site, and in areas affected by the site, will be above the 100-year flood elevation. SWFWMD also requires that there be no net encroachment into the flood plain, up to that encompassed by the 100-year event, which will adversely affect conveyance, storage, water quality or adjacent lands. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's flood-protection standards. The testimony of Mr. Fuxan and Wiregrass' related exhibit, Ranch Ex. 35, purporting to show that in a 25-year, 24-hour storm Saddlebrook's proposed redesign will "flood the [Saddlebrook perimeter] roads and just sheet flow onto the Porter property" is not accurate. As part of its redesign, Saddlebrook will construct an additional berm along the southwestern and southern perimeters of its property. This berm will detain water on Saddlebrook's property during a 25-year, 24-hour storm event and prevent it from "sheet-flowing" onto the Wiregrass property. Water Quality. Under the water-quality standards of the Basis of Review, SWFWMD requires, for systems like Saddlebrook's involving wet detention and isolated wetlands, that the applicant provide sufficient storage to treat one inch of runoff from the basins contributing runoff to the site. This volume must be discharged in no less than 120 hours, with no more than one-half of the volume being discharged within the first 60 hours. The evidence presented at the formal hearing demonstrated that Saddlebrook's application satisfies SWFWMD's water-quality standards. Wetland Impacts. Under the wetland-impacts standards of the Basis of Review, SWFWMD requires that the applicant provide reasonable assurance that the proposed system will not adversely impact on-site and downstream wetlands. The evidence presented at the formal hearing demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to on-site wetlands. Saddlebrook's proposed redesign will impact only approximately .167 acres of on-site wetlands, for which Saddlebrook will fully mitigate by creating .174 acres of forested wetlands and buffer area. The evidence presented at the formal hearing also demonstrated that Saddlebrook has provided reasonable assurance that the proposed redesign will cause no adverse impacts to off-site wetlands. Reasonable assurance that off- site wetlands will not be adversely impacted was demonstrated by, among other things, evidence establishing that: (1) discharge points will not change under the proposed condition; (2) discharge elevations will be reasonably similar under the proposed condition; (3) there will be no significant variation in the water fluctuations in the wetlands adjacent to the south and west outfalls as a result of the proposed condition; (4) the drainage basin areas will be reasonably similar under the proposed condition; and (5) the proposed redesign will satisfy SWFWMD's water quality requirements. Wiregrass' Petition. In its Petition for Formal Administrative Hearing, Wiregrass focused primarily on water quality issues and stormwater runoff rates (or peak flow discharges), alleging the following "ultimate facts" which it claimed "entitle [it] to relief": The application, as submitted, contains insufficient storage to meet water quality criteria. The application, as submitted, will result in storage volumes on the project site which will not be recovered within 72 hours [sic] as required by the DISTRICT criteria. The application, as submitted, contains calculations based on erroneous hydraulic gradients. The application, as submitted, will result in storage volumes insufficient to meet water quality criteria as required by DISTRICT criteria. Post development stormwater runoff rates are underestimated in the application, resulting in system design with insufficient retention storage capacity to meet the DISTRICT's water quantity criteria. The failure to store stormwater or irrigation runoff impacts the substantial interest of the RANCH in that it deprives it of groundwater resources necessary for the successful operation of the ranch. Further, the lack of storage of stormwater and irrigation water is a prohibited waste of the water resources. At the formal hearing, Wiregrass presented no evidence to support any of the foregoing allegations of its Petition. Objections Raised by Wiregrass At The Hearing. At the final hearing, Wiregrass' opposition to Saddlebrook's permit application focused on three different grounds: For purposes of evaluating peak flow discharges, SWFWMD does not have jurisdiction to use a pre-development date prior to October 1, 1984. Under F.A.C. Rule 40D-4.301(1)(i), which provides that an applicant must give reasonable assurance that the surface water management systems "is consistent with the requirements of other public agencies," SWFWMD must apply not only its own permitting criteria but also those of other governmental entities, including county planning ordinan Under F.A.C. Rule 40D-4.301(1)(b), which provides that a permit application must give reasonable assurances that the surface water management system "will not cause adverse water . . . quantity impacts", SWFWMD must consider whether the annual volume of runoff will increase as a result of the proposed surface water management system. None of the foregoing objections was raised in Wiregrass' Petition as a basis for denying Saddlebrook's application. (Annual volume was alluded to in the Petition only as being pertinent to the question of Wiregrass' "substantial interest" for purposes of standing.) In any event, for the reasons set forth below, each of these objections was refuted by the evidence presented at the formal hearing. The 1973 Pre-Development Date. In their civil action against Saddlebrook, the Porters took the position that Saddlebrook's surface water management system should be redesigned so that discharges approximate those levels existing in 1973, before development of the Saddlebrook property. Dr. Gerald Seaburn, a hydrologist retained by the Porters, testified in the civil action that 1973 is the appropriate pre-development date for purposes of evaluating Saddlebrook's peak flow discharges. David Fuxan, a civil engineer retained by the Porters, took the position in the civil action that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. At the formal hearing in this proceeding, Mr. Fuxan testified that it is still his position that Saddlebrook should modify its surface water management system so as to return peak flow discharges to 1973 levels. By letter from the Porters' counsel to SWFWMD dated January 31, 1990, the Porters provided their express consent to SWFWMD's use of 1973 as the pre- development date for evaluating those discharges relevant to Saddlebrook's MSSW permit application. Use of a 1984 "pre-development" date would prevent Saddlebrook from making the modifications the Porters claim in the civil litigation that it must make. Saddlebrook's existing system, about which the Porters complain in the civil litigation, is in all material respects the same system that was in place on October 1, 1984. Use of this existing system as the benchmark of comparison for attenuation of peak flows, therefore, would mean that substantial modifications to the existing system could not be made without substantially increasing retention storage on Saddlebrook. Substantially increasing retention storage on Saddlebrook is not possible due to the high water table and proximity of the lower aquifer. See Finding of Fact 70, below. In addition, a primary claim of the Porters in the civil action is that duration of flow under Saddlebrook's existing system exceeds 1973 levels and has resulted in expanded wetlands on the Porter property. But duration of flow and peak flow discharges are inversely related: duration of flow can be decreased only if peak flow discharges are increased. Accordingly, the only way that Saddlebrook can reduce the duration of flow onto Wiregrass to 1973 levels, as the Porters have demanded, other than increasing retention storage on Saddlebrook, is to return peak flow discharges to 1973 levels. Other Governmental Agencies' Requirements. F.A.C. Rule 40D-4.301(1)(i) provides that a permit applicant must give reasonable assurance that the surface water management system "is consistent with the requirements of other public agencies." SWFWMD has consistently interpreted this provision to be "advisory", i.e., to apprise applicants that they must also comply with other applicable laws and that issuance of an MSSW permit by the District does not relieve them of the responsibility to obtain all necessary local and other permits. SWFWMD's long-standing and consistently-applied interpretation and practice is not to require applicants to prove compliance with the regulations of other govermental agencies in order to obtain an MSSW permit. There are two primary reasons for this interpretation and practice. First, the Southwest Florida Water Management District includes 16 counties and 96 municipalities. In addition, other state and various federal agencies have jurisdiction within its territory. It is impracticable for SWFWMD to become familiar with, and to apply, the permitting and other regulations of more than 100 other agencies. Second, SWFWMD has concluded that, under Part 4 of Secton 373 of the Flordia Statutes, it does not have authority to deny a permit application based on its interpretation of another governmental agency's regulations. In any event, the evidence demonstrates that Saddlebrook has provided reasonable assurance that the proposed redesign will be "consistent with the requirements of other public agencies" as provided in F.A.C. Rule 40D- 4.301(1)(i). Limiting Condition No. 3 of the proposed permit requires that Saddlebrook must comply with Pasco County and other local requirements: The Permittee shall comply with all applicable local subdivision regulations and other local requirements. In addition the permittee shall obtain all necessary Federal, State, local and special district authorizations prior to the start of any construction or alteration of works authorized by this permit. In addition, Standard Condition No.3 ensures that SWFWMD approval will not supersede any separate permitting or other requirements imposed by Pasco County: The issuance of this permit does not . . . authorize any . . . infringement of federal, state or local laws or regulations. (Emphasis added.) Finally, the Pasco County ordinance upon which Wiregrass relies imposes requirements that are in substance identical to SWFWMD's with respect to MSSW permit applications. Saddlebrook's compliance with SWFWMD's regulations likewise would satisfy the substance of the requirements of the county ordinance. Annual Volume of Runoff. F.A.C. Rule 40D-4 (incorporating the Basis of Review) does not address, and SWFWMD does not regulate, the annual volume of runoff in open drainage basins. If annual volume of runoff is relevant under Rule 40D-4.301, as Wiregrass contends, that rule requires only that the applicant provide reasonable assurance that "the surface water management system" will not cause adverse quantity impacts. Saddlebrook's existing surface water management system has not caused a significant increase in the annual volume of runoff onto Wiregrass' property. The increase in the annual volume of runoff from Saddlebrook that has occurred over the pre-development 1973 condition has resulted from the urbanization of Saddlebrook's property. The increase in the annual volume of runoff from Saddlebrook over that existing prior to development (1973) is approximately 3.4 inches. This increase is only a small fraction of the natural year-to-year variation in runoff resulting from differences in rainfall alone. Rainfall can vary up to 30 inches on an annual basis, from 40 to 70 inches per year. The resulting year-to-year variations in runoff can total as much as 20 inches. The approximately 3.4 inches increase in the annual volume of runoff from Saddlebrook due to urbanization has caused no adverse impact to Wiregrass. The natural drainage system on the Wiregrass property has in the past and throughout its history received and handled increases in the annual volume of runoff of up to 20 inches due to rainfall differences. Such increases simply flow through Wiregrass' property. Of the approximately 3.4 inch increase in annual runoff due to urbanization, only approximately one-third of an inch is due to the filling in of bayheads by Saddlebrook's prior owner. This increase is insignificant and has not caused a substantial adverse impact to Wiregrass. Any reduction of storage resulting from the filling of bayheads will be more than compensated for under the proposed redesign. Storage on Saddlebrook's property will be increased by approximately 35 percent under the proposed condition over that existing in 1973, before the bayheads were filled. In open drainage basins, like Saddlebrook's, downstream flooding is a function of the rate of peak flow of discharge, not the annual volume of runoff. This is one of the reasons why, in the case of open drainage basins, SWFWMD regulates peak flow discharges and not the annual volume of runoff. Because Saddlebrook's proposed redesign will attenuate peak flow discharges to those levels that existed in the pre-devlopment 1973 condition, Saddlebrook has provided reasonable assurance that there will not be increased flooding on Wiregrass' property in the future. The evidence does not establish that Wiregrass has suffered, or will suffer, any adverse impact due to an increase in the annual volume of runoff from Saddlebrook as a result of the design, or redesign, of the system, or as a result of urbanization, or otherwise. It is not possible to design a surface water management system at Saddlebrook that would reduce the annual volume of runoff. Such a system, which involves the percolation of surface water from retention ponds into a deeper, aquifer system, requires a deep water table. At Saddlebrook, the water table is near the ground surface. As a result, it is not possible to store a significant quantity of water in retention ponds between storm events. In addition, the water levels in the deeper and the shallower aquifer systems at Saddlebrook are approximately the same and, therefore, there is insufficient hydraulic pressure to push the water through the confining layer between the two systems and into the deeper aquifer system.
Recommendation Based on the foregoing Findings of Fact and Conclusions of Law, it is recommended that the Southwest Florida Water Management District enter a final order granting Saddlebrook's application for surface water management permit no. 497318.00, subject to the terms and conditions in the SWFWMD Staff Report. RECOMMENDED this 31st day of March, 1992, in Tallahassee, Florida. J. LAWRENCE JOHNSTON Hearing Officer Division of Administrative Hearings The DeSoto Building 1230 Apalachee Parkway Tallahassee, Florida 32399-1550 (904) 488-9675 Filed with the Clerk of the Division of Administrative Hearings this 31st day of March, 1992. APPENDIX TO RECOMMENDED ORDER, CASE NO. 91-3658 To comply with the requirements of Section 120.59(2), Fla. Stat. (1991), the following rulings are made on the parties' proposed findings of fact: Petitioner's Proposed Findings of Fact. 1.-4. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Accepted and incorporated to the extent not subordinate or unnecessary. 7.-9. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. 12.-13. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but not necessary. The extent of the wetland expansion is rejected as not proven and contrary to the greater weight of the evidence. The rest is accepted. However, the increased volume is due in large part to urbanization, not to the surface water management system. It also is due in part to alterations to the property done by the Porters. Accepted but subordinate and unnecessary. Accepted. However, this would occur only during a 25-year, 24-hour storm event, and there was no evidence that one has occurred or, if it has, whether Mr. Porter was there to observe it. 18.-20. Accepted but subordinate and unnecessary. Characterization "much of" is rejected as not proven and contrary to the greater weight of the evidence. Otherwise, accepted but subordinate and unnecessary. Accepted and incorporated. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence. Rejected as not proven and contrary to the greater weight of the evidence that lichen lines, by themselves, are ordinarily are sufficient to set jurisdictional lines. 26.-29. Rejected as not proven and contrary to the greater weight of the evidence. Even if it were proven that the wetlands had expanded, it was not proven, and is contrary to the greater weight of the evidence, that Saddlebrook (and, especially, Saddlebrook's surface water management system) caused the expansion. First sentence, accepted but cumulative. The rest is rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. In any event, both factors are undeniably significant. 32.-34. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. 39.-41. Rejected as not proven and contrary to the greater weight of the evidence that SWFWMD does not apply it. The evidence was that SWFWMD interprets it differently than Wiregrass proposes and applies its own interpretation. Under the SWFWMD interpretation, the permit conditions requiring compliance with other legal requirements constitute the necessary "reasonable assurance." In addition, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and the Pasco County ordinance has been considered as part of this proceeding. Rejected as not proven and contrary to the greater weight of the evidence. Again, SWFWMD's review and evaluation is not complete until this formal administrative proceeding is completed, and annual volume has been considered as part of this proceeding. That consideration has affirmed SWFWMD's position that, at least in this case, the proposed stormwater management system does not cause an increase in annual volume that would result in denial of the application. Accepted but subordinate and unnecessary. Rejected as not proven and contrary to the greater weight of the evidence. First sentence, accepted (although the characterization "far exceed" is imprecise) and incorporated. Second sentence, rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary that no "stipulation" was entered into. But the evidence is clear that Wiregrass, Saddlebrook and SWFWMD all agreed to the use of 1973 as the point of comparison for peak flow discharges. Rejected as not proven and contrary to the greater weight of the evidence. Accepted but subordinate and unnecessary. Respondents' Proposed Findings of Fact. The proposed findings of fact contained in the Proposed Recommended Order of Respondents Saddlebrook Resorts, Inc., and Southwest Florida Water Management District are accepted and incorporated to the extent not subordinate or unnecessary.

The Issue This case presents two questions for consideration. The first question concerns the Petitioners' contention that the grant of the permit at issue must be considered contemporaneously with the matters of file in the application made by the Respondent, The Deltona Corporation, with the Respondent, State of Florida, Department of Environmental Regulation, File No. 64-24208, pending before the Department. From the point of view of the Petitioners, should this contemporaneous review process be afforded, then the current permit would not be granted due to the alleged deficiencies associated with the application, File No. 64-24208. The second question to be answered in this case concerns the dispute between the Respondents on the issue of water quality monitoring as a condition to granting the permit sought herein. The Respondent Department would have the applicant monitor in six lakes in the area of the project and the applicant would restrict its monitoring activity to three lakes in the project area. The Petitioners support the Department in its position on the monitoring question. 1/
Findings Of Fact The Respondent, The Deltona Corporation, has made application with the Respondent, State of Florida, Department of Environmental Regulation, to effect drainage system improvements to a land locked conveyance network which consists of the enlargement and regrading 990 lineal feet of existing channel cross- section and the installation of additional culverts and control structures at road crossings. The project also involves repairs and replacement of a damaged culvert. The work would be accomplished by land based equipment transported to the work site by existing overland routes. The excavated sand fill would be placed on upland property owned by The Deltona Corporation. The details of the project and data related to the geographical area may be found in the Joint Exhibit I admitted into evidence. The date of the application for permit is December 12, 1979. On January 25, 1980, the Department of Environmental Regulation sent out a notice of the pending review by the Department of the permit application. After receipt of that notice, attorney for the Petitioners, on February 12, 1980, wrote to the Department expressing the objection to the project made by property owners in the area of the project site, together with a list of those owners found in an attached Petition of owners' names and addresses. A copy of this letter and attached Petition may be found as Joint Exhibit No. VII admitted into evidence. Subsequent to the receipt of the statement of objections, the Department issued a construction permit dated April 30, 1980, subject to conditions. A copy of this permit may be found as Joint Exhibit No. VIII admitted into evidence. The Petitioners, through their counsel, then filed a formal petition dated May 6, 1980, which was the vehicle utilized in establishing the details of this dispute and was the basis for the Department Secretary forwarding the case to the Division of Administrative Hearings for consideration by a hearing officer in keeping with the provisions of Section 120.57, Florida Statutes. The hearing was conducted on October 16, 1980, and the Petitioners' position was more specifically defined in the course of that hearing and the claim as described in the issue statement of this order constitutes the substance of the Petitioners' position. 2/ Joint Exhibit No. I; petitioners' Exhibit No. 1 and Respondent Deltona's Exhibits 1, 2 and 4 constitute sketches and aerial photographs of the general project area. Joint Exhibit No. 1 identifies the work area with more particularity. Respondent's Exhibit No. 2 indicates the desired flow pattern of the water through the various lake systems and indicates whether the flow is by gravity flow or pump flow. This drawing depicts the proposed channels and structural improvements that would be involved. The Department has indicated that all the regulatory concerns which it has about the project associated with Permit No. 64-26478-4E, the permit in question, have been adequately addressed, subject to the conditions set forth in the permit document. Joint Exhibit Nos. V and VI; Respondent Deltona's Exhibit Nos. 5, 6 and 7; and the Petitioners Exhibit No. 2 are exhibits pertaining to water quality concerns, to include sample results. The testing and other information provided indicates that the project as contemplaced, would meat the regulatory parameters set forth in Chapter 403, Florida Statutes, and Chapters 17-3 and 17-4, Florida Administrative Code. The Department in expressing its concern that continued water quality monitoring be conducted has indicated that it feels that future periodic monitoring should be done in Jenkins Pond, Lake Big, Lake Diana, McGarity Lake, Sidney Lake and Lake Mitnik. The Respondent Deltona would only conduct this monitoring in the first three lakes named. By looking at the Respondent Deltona's Exhibit No. 2, it could be seen that all of the aforementioned lakes would be in the same basic flow pattern. Of the system of lakes, the area around McGarity Lake is the most highly developed and and has the greatest potential for causing unacceptable pollution. That pollution could be carried through the other lakes within the system as described in view of the potential of the system, if the project is built, to convey a greater volume of water at a higher rate of flow. A more expansive water quality monitoring system within six lakes as opposed to three lakes would increase the opportunity to discover potential hazards from pollutant at an earlier data. This is particularly so by using lakes such as McGarity Lake where there is a higher level of developmental build-out.
The Issue The issue is whether the Southwest Florida Water Management District (District) should issue water use permit (WUP) No. 2004912.006 to the City of Lakeland (City), and if so, how much water should be allocated under the permit and what conditions should be imposed on the allocation, particularly in regard to withdrawals from the City's Northeast Wellfield (NEWF).
Findings Of Fact Introduction This is an unusual case in that the District gave notice of its intent to issue a permit that the City does not want and that the District staff testified that the City is not even entitled to based upon the information submitted prior to and at the final hearing. That said, there is no disagreement between the parties that a permit should be issued to the City. Indeed, despite the District Staff's testimony that the City failed to provide “reasonable assurances” prior to or at the final hearing on a variety of issues, the District takes the position in its PRO that a permit should be issued to the City, subject to various conditions and limitations. There is also no disagreement between the parties that the permit should include an allocation of 28.03 mgd from the City’s Northwest Wellfield (NWWF). The main areas of disagreement between the District and the City are the duration of the permit; the total allocation of water under the permit; and, perhaps most significant, the total allocation from the NEWF. Parties The City is an incorporated municipality located in Polk County. The City is within the boundaries of the District and is within the Southern Water Use Caution Area (SWUCA) designated by the District. The City is the applicant for the WUP at issue in this case, No. 20004912.006. The City operates a public water utility that provides potable water and wastewater services to customers in and around the City. The utility’s water service area extends beyond the City limits into surrounding unincorporated areas of Polk County. The District is the administrative agency responsible for conservation, protection, management and control of the water resources within its geographic boundaries pursuant to Chapter 373, Florida Statutes, and Florida Administrative Code Rule Chapter 40D. The District is responsible for reviewing and taking final agency action on the WUP at issue in this case. Stipulated Facts The parties stipulated that the City’s substantial interests have been adversely affected by the District’s intent to issue the proposed permit, and that the proposed permit is different from the permit that the City applied for. The parties also stipulated that there is reasonable assurance that the City’s proposed water use will not interfere with a reservation of water as set forth in Florida Administrative Code Rule 40D-2.302; that the proposed use will not significantly induce saline water intrusion; that the proposed use will incorporate the use of alternative water supplies to the greatest extent practicable; and that the proposed use will not cause water to go to waste. The City’s Wellfields Overview The City obtains the water that its water utility provides to its customers from two wellfields, the NWWF and the NEWF. The NWWF is located north of Lake Parker in close proximity to Interstate 4 and Kathleen Road. It provides water to the Williams Water Treatment Plant, from which the water is distributed throughout the City water utility’s service area. The NWWF is located on the Lakeland Ridge, which is a geographic feature that is approximately 250 to 260 feet above sea level. The Lakeland Ridge has a thick clay intermediate confining unit that isolates the surficial aquifer from the underlying aquifers. The NEWF is located to the north of Interstate 4, adjacent to Old Polk City Road. It provides water to the Combee Water Treatment Plant (Combee), from which the water is distributed throughout the City water utility’s service area. The NEWF is located at an elevation of approximately 135 feet above sea level. The surficial aquifer at the NEWF is relatively thin, and the intermediate confining unit at the NEWF is not as thick as it is at the NWWF. The Upper Floridan Aquifer (UFA) begins at approximately 65 below land surface at the NEWF. The City’s water treatment plants are traditional lime softening plants and are not able to treat brackish groundwater or surface water to the extent necessary for human consumption. It would be cost-prohibitive to implement a process to treat brackish water at the plants. Relevant Permitting History The City’s water utility has been in operation for more than 100 years, and the NWWF has been in operation since at least the early 1980’s. The earliest permit for the NWWF contained in the record is permit No. 204912, which was issued by the District in January 1987. The permit authorized average annual withdrawals of 28.3 mgd, and had an expiration date of January 1993. The NEWF was first permitted by the District in December 1989. The permit, No. 209795.00, authorized the City to pump an average of 9.0 mgd from the NEWF. The permit had a six-year duration, with a December 1995 expiration date. The permits for the NWWF and the NEWF were combined into a single permit in October 1993. The permit, No. 204912.03, authorized the City to pump a total of 28.1 mgd, with 9.0 mgd from the NEWF. The permit had a 10-year duration, with an October 2003 expiration date. In December 2002, the City's WUP was administratively modified pursuant to the District’s SWUCA rules. The modified permit, No. 20004912.004, did not change the permitted quantities at the NEWF or the 2003 expiration date, but the total allocation was reduced to 28.03 mgd. In October 2003, prior to the expiration of the existing permit, the City submitted an application to renew and modify its WUP permit. The application requested a 20-year permit with a total allocation of 32.8 mgd, with up to 16.0 mgd from the NEWF. During the permit review process, the City amended its application to increase the requested total allocation by 4.0 mgd (from 32.8 mgd to 36.8 mgd) and to decrease the requested duration of the permit by five years (from 2023 to 2018). The 36.8 mgd requested by the City was to be allocated between the NWWF (28.03 mgd) and the NEWF (8.77 mgd). The City supplemented its application during the permit review process in response to multiple requests for additional information and clarification from the District. The information provided by the City in support of the application is extensive; the “permit file” received into evidence consisted of approximately 2,500 pages, and the entire file is approximately twice that size.2 The review process culminated in what the District staff considered to be a “negotiated permit”3 that would initially authorize pumping of 33.03 mgd, with 28.03 from the NWWF, 1.5 mgd from the NEWF, and 3.5 mgd from a production well to be constructed at Combee. The proposed permit includes a phasing schedule that would allow for increased withdrawals -- up to 35.03 mgd total and 4.0 mgd from the NEWF4 -- if the City is able to demonstrate to the District’s satisfaction that the increased pumping will not cause adverse environmental impacts. The District gave notice of its intent to issue the proposed permit on December 29, 2006, and the permit was placed on the “consent agenda” for the District Governing Board’s meeting on January 30, 2007. On January 23, 2007, before the proposed permit was considered by the Governing Board,5 the City timely filed a petition challenging the proposed permit. The petition alleges that the proposed permit does not allocate sufficient water to meet the City's projected population demands in 2018 and that it does not allocate water quantities from the NEWF and the NWWF in the manner requested by the City. The NEWF The NEWF is approximately 880 acres in size. Wetlands comprise approximately half of the site. The NEWF is located within the boundaries of the Green Swamp, which is an area of critical state concern (ACSC) designated under Chapter 380, Florida Statutes. The Green Swamp is a hydrologically and environmentally important feature of central Florida encompassing thousands of acres of cypress wetlands, marshes, and forests. In 1992, a task force recommended that public water supply wellfields “of capacity greater than 1.8 mgd (average 3.6 mgd maximum)” from the UFA be discouraged in the Green Swamp ACSC in favor of wells from the Lower Floridan Aquifer in order to “mitigate drawdown impacts to the surficial aquifer system and resulting dehydration of wetlands . . . .” There is no evidence of that recommendation being formally adopted by the District or any other governmental agency, and the District does not have more stringent permitting criteria for WUP applications in the Green Swamp, except that it considers potential adverse impacts to all isolated wetlands and not just those larger than one-half acre in size.6 The City installed five 16-inch production wells at the NEWF, along with a number of associated monitoring wells. The production wells, which are cased to approximately 120 feet with a total depth of approximately 750 feet, pump water from the UFA. Pumping at the NEWF started in October 2005. The City has been pumping 4.0 mgd from the NEWF since that time. The City has spent over $34 million to bring the NEWF into service. The costs directly related to the acquisition of the NEWF site and the installation of the wells at the site account for approximately $7.6 million of that amount; the remainder of the costs are for associated infrastructure, such as the installation of water lines from the NEWF site and the construction of Combee. The wetlands on the NEWF site are predominantly isolated cypress wetlands, although there are some connected systems. Isolated wetlands are more susceptible to impacts from water deprivation than are connected wetland systems. The uplands on the NEWF site consist primarily of open pasture and fields and areas of planted pines. Extensive drainage improvements were constructed on the NEWF site between 1941 and 1980 when the site was being used as improved pastureland for cattle grazing and managed woodland for logging and silviculture. The improvements included the construction of a network of drainage ditches, culverts, roads, a grass landing strip, and a gas pipeline. The intent and effect of the drainage improvements was to remove surface water from the onsite wetlands. Historical aerial photographs show that these efforts were successful. The wetlands on the NEWF were adversely impacted by the drainage improvements, but for the most part, they are still functioning, albeit low-quality wetlands. The extensive ditching on the NEWF site continues to have an adverse impact on the wetlands even though the ditches have not been maintained and do not function as efficiently as they once did. The planted pine trees on the NEWF site may also be adversely affecting the wetlands through increased evapotranspiration from the surficial aquifer. However, the evidence was not persuasive regarding the extent of the impact from evapotranspiration. The present condition of the wetlands at the NEWF is not the result of recent activity. The biological indicators in the wetlands (e.g., adventitious roots on cypress trunks, large oak trees in the wetlands, red maple trees in areas that had at one time been dominated by cypress trees) show that the degraded condition of the wetlands dates back decades. The progressive draining and degradation of the wetlands caused by the ditching and other drainage improvements constructed on the NEWF site is apparent in the historic aerial photographs of the site. The size of the wetlands and the “hydrologic signatures” (e.g., standing water around the rims of wetlands and across the site, extensive cypress canopies, etc.) visible on earlier aerial photographs are less visible or non- existent in more recent aerial photographs. The wetlands on the NEWF site have shown no biological indicators of impacts from the pumping at the NEWF that started in October 2005. This does not necessarily mean that the pumping is not impacting the wetlands because the parties' experts agree that it can take many years for such biological indicators to appear. The more persuasive evidence establishes that the historical drainage improvements on the NEWF site were the primary cause of the degraded condition of the wetlands.7 The more persuasive evidence also establishes that unless altered, the drainage improvements on the NEWF site will continue to have an adverse effect on the wetlands. The City proposed a conceptual Wetland Improvement Plan (WIP) that is designed to restore and enhance the wetlands on the NEWF. A central component of the WIP is the reengineering and alteration of the drainage features by installing “ditch blocks” in some areas and culverts in other areas. The WIP also includes not replanting the pine trees on the NEWF site once the existing planted pines are harvested. The ditch blocks and other modifications to the drainage features are intended to hold water on the NEWF site and redirect it to the wetlands. This will help to hydrate the wetlands, increase soil moisture levels, and allow more water to percolate into the surficial aquifer following rain events. The District staff expressed some concerns with the City’s WIP at the final hearing, but acknowledged that the plan’s “conception . . . has a lot of merit.” Indeed, in its PRO, the District recommends the “installation of ditch blocks and similar measures at the [NEWF] site.” The WIP, if properly implemented, has the potential to enhance the wetlands by returning them to a more natural condition. The City will likely need an Environmental Resource Permit (ERP) from the District before any system of ditch blocks can be installed. The details of the WIP can be worked out during the ERP permitting process.8 A good monitoring plan is part of providing reasonable assurances. The parties agree that a monitoring plan should be included as a permit condition, and the EMMPs attached to the parties’ respective PROs appear to be materially the same. The City has monitored the wetlands at the NEWF since 1994, pursuant to a specific condition in the 1993 WUP permit. The methodology used by the City to monitor the wetlands was approved by the District, and despite the fact that the City has submitted biannual monitoring reports to the District for almost 14 years, the District expressed no concerns regarding the methodology or results of the monitoring until recently. The District commenced its own wetland assessment procedure at the NEWF in May 2007, which included setting “normal pools” in several of the wetlands. “Normal pool” describes the level at which water stands in a wetland in most years for long enough during the wet season to create biological indicators of the presence of water. The establishment of normal pools was part of the District’s efforts to establish the “existing natural system” against which any post-withdrawal adverse impacts at the NEWF would be measured in accordance with Section 4.2 of the Basis of Review for Water Use Permit Applications (BOR).9 Normal pools could not be established in several of the wetlands because there was no measurable standing water above the surface in the wetland. District staff observed similar conditions –- i.e., no standing water in the wetlands –- on at least one occasion following a significant rain event prior to the start of pumping at the NEWF. The District does not have a rule governing the setting of normal pools, but the City’s experts did not take issue with the normal pools set by the District or the methodology used by the District to set the normal pools. The EMMP proposed by the City is an extensive monitoring plan that incorporates a series of onsite monitoring wells, wetland monitoring stations for vegetation and hydrogeology, monitoring of pumping rates and pumping data, and monitoring of rainfall data. The EMMP will make use of the extensive data that has been collected on the NEWF site since the 1990’s as well as the normal pools set by the District, and if properly implemented, the EMMP will detect any potential adverse impacts as they occur to allow for remedial mitigation. The District staff acknowledged at the final hearing that the EMMP proposed by the City “with some minor modifications” is an appropriate plan to monitor changes in the wetlands at the NEWF. The necessary "minor modifications" were not explained at the final hearing, and as noted above, there does not appear to be any material difference in the EMMPs attached to the parties’ respective PROs. The Green Swamp is generally viewed as a “leaky” area, with little or no confinement between the surficial aquifer and the Floridan aquifer. Regional data, including studies by the United States Geologic Survey (USGS) and the District, reflect that the NEWF is located in a “transitional area” between areas of little or no confinement to the north, northwest, and east of the NEWF and areas of thicker confinement to the south. However, at least one study (published in 1977 USGS report) shows the NEWF in an area designated as "poor" for its relative potential for downward leakage. Regional data may be used to gain knowledge about the aquifer properties at a potential well site, but such data is not a valid substitute site-specific data. Indeed, the location of the NEWF in a “transitional area” makes site-specific data even more important. The City used geologic cross-sections (e.g., soil borings and core samples) at the NEWF to determine the site’s lithologic characteristics. By contrast, the District relied primarily on USGS reports and other regional data to postulate as to the lithologic characteristics of the NEWF. As a result, the City’s position regarding the lithologic characteristics of the NEWF was more persuasive than the District’s position. The lithology of the NEWF site consists of a shallow, sandy surficial aquifer, which extends to a depth of 3 to 5 feet, proceeding downward to sandy clay and clay sand semi- confining layers, alternating with impermeable clay units, interspersed with an intermediate aquifer composed of sandy clays and clay sands that contain water, proceeding downward to the limestone of the UFA. The presence of clay layers between the intermediate aquifer and the UFA, together with clay layers between the intermediate aquifer and the surficial aquifer, provide two layers of protection between the pumped aquifer and the surficial aquifer and wetlands, and serve to ameliorate any impacts to the surficial aquifer caused by withdrawals from the UFA. “Leakance” is a measure of vertical conductivity that describes the rate at which water flows through a confining unit. As a result, leakance is one of the most important factors to consider when modeling surficial aquifer impacts and potential wetland impacts from groundwater pumping. Generally, a higher leakance value is an indication of a “leakier” system with less confinement between the surficial aquifer and the UFA. The “leakier” the system, the greater the impacts of pumping on the surficial aquifer will be. The District contends that the confining unit underlying the NEWF is “leaky” and that the pumping at the NEWF is likely to directly and adversely affect the onsite wetlands. However, the more persuasive evidence establishes that the lower leakance value derived by the City based upon the site-specific lithology of the NEWF and the data from the aquifer performance tests (APTs) conducted at the NEWF is more accurate than the higher leakance value urged by the District. The purpose of an APT is to determine the hydrologic parameters of an aquifer. In particular, an APT is used to determine the transmissivity, leakance, and storage values of the aquifer. Transmissivity is a measure of how easily water flows through the ground, and storage is a measure of the amount of water in the porous spaces of the aquifer. Generally, a higher transmissivity value and a lower storage value indicate better confinement. There have been three APTs conducted at the NEWF. The first APT (APT-1) was conducted in 1989 as part of the initial permitting of the NEWF. A high transmissivity value and a low storage value were calculated in APT-1. A leakance value was not calculated. The results of APT-1 were presented to the District to justify the City’s request to pump 9.0 mgd from the NEWF, which the District approved. The 1993 permit combining the NWWF and the NEWF required the City to conduct a long-term APT in order to “determine the leakance parameter between the surficial and intermediate aquifers and the leakance parameter between the intermediate and Upper Floridan aquifers.” The permit stated that if the hydrologic parameters obtained in the APT were different from those used in the model submitted in support of the initial WUP, the City would have to revise the model and, if necessary, modify the WUP to reduce withdrawals. This second APT (APT-2) was a seven-day test conducted by the City in January 2001 in accordance with a methodology approved by the District. An “exceedingly low” leakance value of 4.5 x 10-4 gallons per day per cubic foot was calculated in APT-2. The transmissivity and storage values calculated in APT- 2 were essentially the same as the values calculated in APT-1. The District expressed concerns with the results of APT-2, and in December 2001, the District advised the City that it should “proceed with caution during the planning of infrastructure (pipelines) for the [NEWF]” because the “wellfield may not be able to produce the volume of water the City has stated that would like from the wellfield, without causing adverse impacts.”10 Based upon these concerns, the District conducted an APT (APT-3) at the NEWF in April and May 2003. The parties’ experts agree that data from APT-3 is reliable, but the experts disagree in their interpretation of the data, particularly in regards to the leakance value. The City’s experts calculated a leakance value of 1.4 x 10-4 feet per day per foot, which is a low leakance value. The expert presented by the District, Dann Yobbi, calculated a higher leakance value of 3.4 x 10-3 feet per day per foot, which suggests relatively “leaky” aquifer. The leakance value calculated by the City’s experts is more persuasive than the value calculated by Mr. Yobbi because Mr. Yobbi did not “de-trend” the data from APT-3 based upon the general declines in water levels occurring at the time of APT-3. Indeed, Mr. Yobbi testified that he is in the process of revising his report on APT-3 to address this issue and he acknowledged that the surficial aquifer showed only a “slight response” to the pumping during APT-3. The leakance value calculated by the City’s experts in APT-3 is consistent with the leakance value calculated in APT-2. The transmissivity and storage values calculated in APT-3 are also consistent with the values calculated in APT-1 and APT-2. The reliability of the leakance values and other aquifer parameters calculated by the City’s experts for the NEWF is confirmed by water level data compiled by the City pursuant to the monitoring requirements in the existing WUP. The water level data was collected from monitoring wells at the NEWF in the surficial aquifer, the intermediate aquifer, and the UFA. The City began collecting this data in 1994 and it continues to collect and report the data to the District as required by the existing WUP. The water level monitoring data reflects that the surficial aquifer at the NEWF responds almost immediately to rain events. By contrast, the intermediate aquifer and UFA show a more subdued response to rainfall events, which is indicative of good confinement, especially between the UFA and the surficial aquifer. The water level monitoring data shows that rainfall or lack of rainfall is the major controlling factor relative to the rate of surficial aquifer recharge at the NEWF. The water level monitoring data since pumping began at the NEWF shows that the pumping at 4.0 mgd is having a minimal impact on the surficial aquifer at the NEWF. Indeed, the more persuasive evidence establishes that the general decline in water levels that has been observed in the monitoring wells at the NEWF over the past several years is more likely than not attributable to the severe drought in the area and the onsite drainage features, and not the pumping at the NEWF.11 Moreover, the more persuasive evidence shows that following the start of pumping at the NEWF in October 2005, the water levels in the surficial, intermediate, and Floridan aquifers returned to the historic patterns of up and down response to rainfall events shown throughout the thirteen-year period of record: the surficial aquifer fills quickly (as it receives the rainwater directly) and empties quickly (through a combination of surface drainage, evapotranspiration, evaporation, and leakage), while the UFA responds with more gradual rising and falling (as water enters the aquifer through recharge areas and slowly percolates into the aquifer through more confined areas). The analysis of the water level data collected during APT-3 showed a similar trend in the rates of decline in the surficial aquifer as were reflected in the hydrographic record of the monitoring well data collected by the City since 1994. The natural, post-rainfall rate of decline under non-pumping conditions was consistent with the rate of decline observed during pumping conditions in APT-3. In sum, the interpretation of the water level data by the City’s experts was more persuasive than the interpretation by the District’s experts. Modeling of Predicted Drawdowns and Impacts The City utilized two different models to predict drawdowns from the proposed pumping at the NWWF and NEWF: the USGS “Mega Model” and the District’s District-Wide Regulation Model (DWRM). The models incorporated regional data published by the USGS and the District as well as site-specific data from the NEWF, including the lithologic information collected through soil borings and the hydrologic parameters of the aquifers calculated in APT-3. The models were calibrated and de-trended to remove “background conditions” (e.g., regional water level declines) so that the models would only show the predicted effects of the pumping. Once the calibration was complete, the models were run to simulate the effect of the pumping on the groundwater flows in the area. The models produced contour maps that showed the predicted drawdowns in the surficial aquifer as a result of the pumping. The USGS Mega Model predicted that pumping the NEWF at 8.77 mgd would result in drawdowns of approximately 0.5 foot in the surficial aquifer in and around the NEWF. The DWRM model predicted a 0.18 foot drawdown in the surficial aquifer in and around the NEWF when pumping the NEWF at 4.0 mgd, and a drawdown of 0.4 foot when pumping at 8.77 mgd. The same models were used to predict the “cumulative” drawdowns by taking into account pumping by existing legal users as well as the pumping at the NWWF. The cumulative models assumed pumping of 36.8 mgd from the City’s wellfields. The USGS Mega Model predicted that cumulative drawdowns in the surficial aquifer in and around the NEWF would be an additional 0.3 feet, with 8.77 mgd of pumping at the NEWF. The DWRM model predicted that the cumulative drawdowns in the surficial aquifer in and around the NEWF would be 0.4 foot with 4.0 mgd of pumping at the NEWF, and 0.6 foot at 8.77 mgd of pumping at the NEWF. The City utilized the 1995 data set of existing legal users in its cumulative DWRM modeling because that was the data set provided by the District. The difference between the 1995 data set and the more current 2002 data set is on the order of 20 mgd, which is inconsequential in comparison to the 1.1 billion gallons per day of withdrawals included in the model that are spread over the geographic extent of the District. The predicted drawdowns in the surficial aquifers in and around the NEWF would be considerably greater if the hydrologic parameters calculated by Mr. Yobbi were used in the DWRM model. For example, the District’s modeling predicted drawdowns between 1.0 and 1.2 feet in the surficial aquifer in and around the NEWF when pumping 1.5 mgd from the NEWF, 3.5 mgd from Combee, and 28.03 mgd from the NWWF. The wetlands experts presented by the parties agreed that the level of drawdown predicted by the City at the NEWF has the potential to adversely impact the wetlands on the site. The experts also agreed that there is no bright line as to the amount of drawdown that will adversely impact the wetlands. The City’s expert, Dr. Michael Dennis, testified that drawdowns in the surficial aquifer between 0.18 foot and 0.5 foot “probably” would not affect the wetlands at all, or at least “not measurably.” He also testified that drawdowns between 0.5 foot and one foot “are the drawdowns that you need to be concerned about.” The District’s expert, John Emery, testified that a drawdown in the surficial aquifer of 0.4 foot “could” adversely affect the wetlands if no mitigation is provided, but that a drawdown of 0.2 to 0.3 foot might not.12 The WIP is expected to increase the amount of water that gets to the wetlands on the NEWF site. However, the extent to which the WIP will increase the water levels in the wetlands and offset the predicted drawdowns in the surficial aquifer is unknown at this point. Limiting pumping at the NEWF to 4.0 mgd is reasonable and prudent based upon the uncertainty regarding the effectiveness of the WIP and the experts’ testimony regarding the level of drawdowns that likely would, and would not, adversely affect the wetlands at the NEWF. In sum, the more persuasive evidence establishes that the drawdown predicted at 4.0 mgd of pumping –- 0.18 foot (individually) and 0.4 feet (cumulatively) –- is not likely to adversely impact the already significantly degraded wetlands at the NEWF, particularly if the WIP is properly implemented. Demand Projections The City did not use the full 28 mgd allocated under its existing WUP. It pumped only 21 mgd in the 12 months preceding October 2003, when the permit was scheduled to expire; it pumped only 26 mgd in 2006; and the pumping for 2007 was expected to be approximately 1 mgd lower than the pumping in 2006. The City's WUP application contained population and demand projections for different years in the future. For 2014 (the permit expiration date proposed by the District), the “functional population”13 of the service area was projected to be 183,264 and the average demand was projected to be 29.5 mgd; for 2023 (the original permit expiration date requested by the City), the projections were 203,721 people and 32.8 mgd; and for 2018 (the permit expiration date now requested by the City), the projections were 192,176 people and 30.9 mgd. The projections in the WUP application were prepared in 2003, and City's primary consultant, Charles Drake, testified that the data was “accurate” and “reliable.” However, more recent data shows that the population projections in the WUP application were slightly understated. The more recent data is contained in the “Water Services Territory Population Estimates and Projections” reports prepared by the City's utility department in March 2006 and March 2007. The reports include estimates of the functional population for prior years, and projections of the functional population for future years. The estimates reflect the “actual” population for a given year in the past, whereas the projections reflect the “expected” population for future years. The estimates and projections in these reports, like the projections in the WUP application, were prepared in accordance with the methodology contained in the BOR. The District did not take issue with the projections in the reports or the WUP application. The estimated functional population of the service area in 2003, 2004, 2005, and 2006 exceeded the population projected for those years in the WUP application. On average, the projected populations for each year understated the “actual” populations by approximately 3,500 persons.14 Likewise, the population projections for future years in the March 2007 report are higher than the population projections for the same years in the WUP application. For example, the report projects that the functional population of the service area in 2014 will be 191,208 (as compared to 183,264 in the WUP application), and that population in 2018 will be 203,247 (as compared to 192,176 in the WUP application). The City presented “revised” population projections at the final hearing in City Exhibit 140. The revised projections were based on the projections in the March 2006 report, but also included data from the “water allocation waiting list” that is part of the City’s concurrency management system that was created by the City in response to legislation passed in 2005 requiring local governments to allocate and approve requests for water for new development. The population projections in City Exhibit 140 are 234,959 in 2014; 247,390 in 2018; and 264,556 in 2023. These projections include an additional 43,471 persons related to new development in the concurrency management system, as well as the additional 2,600 to 3,000 persons projected per year in the WUP application and the March 2006 report. The City failed to establish the reasonableness of the revised population projections. Indeed, among other things, the evidence was not persuasive that the additional population attributed to the new development in the concurrency management system is not already taken into account, at least in part, in the annual population increases projected in the March 2006 report.15 The most reasonable population projections for the service area of the City's utility are those in the March 2007 report.16 The record does not contain demand projections directly related to the population projections in the March 2007 report. However, demand projections for those population projections can be inferred from the WUP application (City Exhibit 1(a)(2), at 0036) and City Exhibit 140 (at page 0015). The 2014 projected population of 191,208 in the March 2007 report roughly corresponds to the projected population for 2018 in the WUP application (192,176) for which the projected demand was 30.9 mgd; and it also roughly corresponds to the projected population for 2008 in City Exhibit 140 (193,001), for which the projected demand was 28.7. Thus, in 2014, it is reasonable to expect that demand will be between 28.7 and 30.9 mgd. The 2018 projected population of 203,247 in the March 2007 report roughly corresponds to the projected population for 2023 in the WUP application (203,721) for which the projected demand was 32.8 mgd; and it also roughly corresponds to the projected population for 2009 in City Exhibit 140 (201,983), for which the projected demand was 30.2 mgd. Thus, in 2018, it is reasonable to expect that demand will be between 30.2 and 32.8 mgd. The demand projections in the WUP for 2014 (29.5 mgd) and 2018 (30.9 mgd) fall within the range inferred for the populations in the March 2007 report. Thus, even though the population projections in the WUP application for 2014 and 2018 are understated, the demand projections for those years in the WUP are still reasonable. The demand projections in City Exhibit 140 –- 35.3 mgd in 2014 and 36.6 mgd in 2018 –- are overstated as a result of unreliable population projections upon which they are based. Other Issues Duration of Permit The 1987 permit for the NWWF had a six-year duration, as did the original 1989 permit for the NEWF. The 1993 permit had a 10-year duration, but that permit did not increase the amount of authorized withdrawals; it simply combined the authorizations for the NWWF and the NEWF into a single permit. In this case, the City is requesting a permit that expires in 2018, which was a 15-year duration at the time the application was filed, but now is a 10-year duration. The District is proposing a permit with a six-year duration, expiring in 2014. The District is authorized to approve a WUP with a duration of up to 50 years. The District’s rules provide that the duration of the permit is to be determined based upon “the degree and likelihood of potential adverse impacts to the water resource or existing users.” The District’s rules require that in order for the District to approve a permit with a duration of more than 10 years, the applicant is required to present sufficient facts to demonstrate that such a permit is “appropriate.” Section 1.9 of the BOR provides “guidelines” regarding the duration of permits. The guidelines in the BOR are not binding on the District, but the nearly identical language in Florida Administrative Code Rule 40D-2.321 is binding on the District. The BOR provides that a six-year permit is to be issued for renewal permits “with modification to increase the quantity withdrawn by more than or equal to 100,000 gpd or 10% or more of the existing permitted quantities, whichever is greater.” The BOR and Florida Administrative Code Rule 40D- 2.321(2)(b) also provide that a six-year permit is to be issued “where the potential for significant adverse impacts are predicted.” The renewal permit that the City is seeking requests an increase of 8.7 mgd (from 28.1 mgd to 36.8 mgd) over the existing permitted quantities, which exceeds the 10 percent threshold in Section 1.9 of the BOR. Moreover, there is a potential for significant adverse impact from the renewal permit that the City is seeking. Accordingly, a six-year permit is appropriate under the District’s rules and the guidelines in the BOR. The City failed to demonstrate why a longer permit duration is appropriate under the circumstances of this case. District staff testified at the final hearing that the permit term should be calculated from the date the permit is issued, which will be some point in 2008. Therefore, the permit should have an expiration date of 2014. Offsite Impacts The City used the modeling described above to predict the drawdown in the UFA from the proposed pumping in order to determine whether there will be any adverse impacts on existing legal users. The predicted drawdown in the UFA in the vicinity of the NEWF ranges from 1.6 feet to 2.4 feet with 4.0 mgd of pumping at the NEWF, and between 3.4 feet and 5 feet with pumping at 8.77 mgd. The predicted drawdown in the UFA in the vicinity of the NWWF ranges from 10.0 to 14.0 feet, with 28.03 mgd of pumping at the NWWF.17 These predicted drawdowns are not expected to have any adverse impacts on existing legal users that have wells in the UFA. Most permitted wells in the UFA use vertical turbine pumps, which can easily accommodate fluctuations in water levels of five feet or more. The City has not received any complaints from existing users since it began pumping 4.0 mgd at the NEWF in October 2005. The pumping at the NWWF, which has been ongoing for more than 20 years, has not caused any adverse impacts to existing legal users. The City is required under the existing WUP to respond to any adverse impact complaints from existing legal users, and it is required to implement mitigation, as needed. In short, City is required to do whatever is necessary (e.g., relocating or increasing capacity of pump, lowering pipes) to return any well impacted by the pumping to its prior function. The City did not evaluate the potential impacts of its proposed pumping on unpermitted wells because the District does not maintain a database of unpermitted wells. However, the City acknowledges that if its pumping impacts an unpermitted well, it will be obligated to mitigate those impacts in the same manner that it is required to mitigate impacts to existing permitted users. The predicted drawdowns for water bodies in the vicinity of the NWWF and the NEWF that have designated Minimum Flows and Levels (MFLs) -- Lake Bonny, Lake Bonnett, and the Cone Ranch wetlands -- are minimal, on the order of 0.1 foot. The City evaluated the impacts of pumping on contaminated sites listed by the Department of Environmental Protection (DEP) in the vicinity of the NWWF and NEWF. Based upon the results of the modeling conducted by the City, there is no reason to expect that pumping at the NWWF and/or NEWF will have any measurable impact on those sites or lead to pollution of the aquifer. Potential Impacts of NWWF Pumping The only concern expressed by the District with respect to the pumping at the NWWF relates to the potential environmental impacts of the pumping on Lake Bonny and Lake Bonnett. The City agreed to include those lakes in its EMMP. Combee Combee is located approximately four miles south of the NEWF. There is a relatively thick clay confining unit at Combee, which, according to the District, makes it a better location for water withdrawals than the NEWF. The District conducted an APT at Combee in 2006. The hydrologic parameters derived from the APT, and the “preliminary modeling” performed by the District show that the City may be able to withdraw at least 3.0 mgd from wells at Combee. The proposed permit authorized pumping of 3.5 mgd from Combee. The proposed permit also included a phasing schedule pursuant to which pumping at Combee would be decreased to 3.0 mgd if pumping at the NEWF reached 4.0 mgd. The City expressed an interest in obtaining water from Combee throughout the permitting process. However, the City represented at the outset of the final hearing that the Combee well is “off the table because the City wishes to maximize the withdrawal allocation from [the NEWF].” The City stated in its PRO that it is “willing to consider permitting a production well at [Combee] as a potential mitigation resource, should unexpected adverse impacts require the City to divert production to a back-up resource.” The District stated in its PRO that the Combee well is “available for mitigation purposes," and that the City “should be encouraged to apply for a WUP for withdrawals from Combee up to 3.0 mgd to provide additional mitigation for pumping from the [NEWF].” Pump rotation Rotation of pumping between the wells in a wellfield is a standard practice, and it can be an effective mitigation technique. The City utilizes well rotation programs at the NWWF and the NEWF in order to minimize the stress on the production aquifers. Rotating pumping between the production wells at the NEWF is particularly appropriate because several of the wells are located in very close proximity to wetlands. Rotating the pumping will help to minimize the potential for adverse impacts to the wetlands. The actual rotation schedule is an operational decision that is made based upon observed conditions at the wellfield site, rather than something that is typically included in the WUP. Conservation and Reuse The City has a four-tiered conservation rate structure, modeled after the District’s graduated water-rates prototype. The rate structure imposes higher unit costs as individual consumption increases, thereby discouraging wasteful uses of water. The City has a comprehensive leak detection program aimed at preventing the loss of water within the City’s water distribution system. This program has helped to reduce the per- capita per-day consumption rate for the City by reducing the volume of water that is wasted before it is delivered to the consumer. The City has implemented irrigation restrictions aimed at reducing the quantities of water used by domestic customers for lawn and garden watering. The per capita rate of water consumption is a measure of the effectiveness of a water conservation program; the lower the figure, the better. The City’s per capita rate has increased in recent years, but its adjusted gross per capita rate has decreased. The adjusted gross per capita rate takes into account “significant users,” which are defined as non-residential customers other than golf courses that use more than 25,000 gallons per day or that represent more than five percent of the utility’s annual water use.18 The City’s per capita rate in 2005 was 145.69 gallons per day, and its adjusted gross per capita rate in that year was 132.01 gallons per day. The adjusted gross per capita rate may not exceed 150 gallons per day within the SWUCA. Thus, the City will be required to continue its conservation programs (and implement additional programs, if necessary) to ensure that its adjusted gross per capita rate does not exceed 150 gallons per day over the life of the permit. A portion of the City’s treated wastewater is reused for cooling at the City’s McIntosh Power Plant pursuant to a permit from DEP under Chapter 403, Florida Statutes. The DEP permit, No. FL0039772 (Major), states in pertinent part: Industrial Reuse: Effluent is reused . . . as a non-contact cooling water at the City of Lakeland McIntosh Power Generating Plant. The volume of water used on a daily basis fluctuates on an as needed basis. There are no restrictions on the volume that can be routed to the reuse system. The power plant evaporates water in the cooling process or returns cooling water into the Glendale WWTP for final treatment in the manmade wetlands treatment system. The reuse in the power plant is not required as effluent disposal. . . . . The remainder of the City’s treated wastewater is “blended” with the water used at the power plant in order to meet the conductivity standards in the DEP permit and the conditions of certification for the power plant and/or directly discharged into an artificial wetland system that ultimately discharges to the Alafia River. Section 3.1 of the BOR (at page B3-2) provides that “Water Use Permittees within the SWUCA who generate treated domestic wastewater are encouraged to demonstrate that . . . 50% of the total annual effluent flows is beneficially reused.” (Emphasis supplied). The BOR lists a number of uses of treated wastewater that are considered to be beneficial reuse. The list includes “industrial uses for cooling water, process water and wash waters” and “environmental enhancement, including discharges to surface water to replace withdrawals.” The City’s use of treated wastewater for cooling at the McIntosh Power Plant is a beneficial reuse under the BOR. The treated wastewater directly discharged by the City into the artificial wetland system is not a beneficial reuse under the BOR because it is not replacing surface water withdrawals. The BOR requires all users within the SWUCA to investigate the feasibility of reuse, and requires the implementation of reuse “where economically, environmentally and technically feasible.” The City has not recently undertaken a study or otherwise evaluated the feasibility of increasing its reuse. The draft permit attached to the District's PRO includes a specific condition requiring the City to "provide a comprehensive study of reuse opportunities encompassing the [City's] water, wastewater, and electrical utilities systems" by January 1, 2009.
Recommendation Based upon the foregoing findings of fact and conclusions of law, it is RECOMMENDED that the District issue WUP No. 2004912.006 with the terms and conditions contained in the draft permit attached to the District’s PRO, except that: The 2014 population referenced in the permit shall be 191,208; The adjusted gross per capita rate shall not exceed 150 gallons per day; Special Condition No. 2 shall be amended to authorize withdrawals from the NEWF at 4.0 mgd annual average and 4.8 mgd peak month, and the quantities listed in the Withdrawal Point Table for the NEWF wells shall be adjusted accordingly; Special Condition No. 4 shall be replaced with a reference to the EMMP and the conceptual WIP attached to the City’s PRO, and the list of monitoring stations in the EMMP shall be amended to include Lake Bonny and Lake Bonnet; and An additional specific condition shall be added encouraging the City to pursue a WUP for the Combee site for future water needs and/or for additional mitigation of the impacts of pumping at the NEWF.
